"Thank you ThatBioTutor for your guidance and constant care for us! Classes are really engaging and students should not have to worry about asking the questions they have. Not only that, the student welfare here is great; from the bubble teas to study sessions, it never failed to motivate me. All I have is praise for TBT and I can say that coming here definitely played a big part in my improvement for biology."
~Xiaohan [B3 to A1]
⭐⭐⭐⭐⭐
"He will actually link what we learnt to analogies to really help us contextualise what we’re learning. When we do OEQs, he’ll tell us what is important, so we know what to look out for and what to write in our answers…
On the night of my exam I can easily spam him 10-20 questions and he’ll never fail to reply me with very high quality explanations… despite his busy schedule. That’s something I really appreciated which is the high quality feedback to allow me to clarify misconceptions or answer any doubts… Honestly I didn’t expect myself to improve so much. It was a very fulfilling experience for me."
~Gareth [A1 for Pure Bio]
⭐⭐⭐⭐⭐
"This tuition is so good. It helped me to achieve A1 as a subject I was struggling in and it really affirmed my learning and understanding in the subject. The lessons are fun and engaging and I’ve become a smarter person as of result if it. The resources are a life saver and all you need, making this tuition feel like the ultimate guide to biology."
~Raniya [A1 for Pure Bio]
⭐⭐⭐⭐⭐
"Excellent tutor in terms of the amount of resources he has such papers,notes,flashcards, specialised answers and very helpful and caring and always answers ur questions. Very knowledgeable and has his own personal touch to everything he does and genuinely cares for the students. Lessons are very beneficial and 100% would recommend for O level taking students. He got me from a C6 in sec 3 EOY to A2 in O level 🙏"
~Aryan [C6 to A2]
⭐⭐⭐⭐⭐
"Even though he’s young, he has a lot of expertise on this topic, in that he studies really hard to fully understand the syllabus, which allows him to teach the students really well in the ever changing syllabus…
Overall I’m really satisfied with my experience at thatbiotutor, because he has really helped me achieve my goals of understanding bio topics and improve on my grades, which are the 2 problems I had at the beginning."
~Isaac [E8 to A2]
⭐⭐⭐⭐⭐
"Fantastic and dedicated tuition teacher! He really goes the extra mile ensuring that his students are given the best help they can possibly get. He never fails to think of memory shortcuts making concept much easier to understand and digest. He plans his lesson such that it requires everyone to be participative all while balancing studying and fun!"
~Rui En [B4 to A2]
⭐⭐⭐⭐⭐
"ThatBio Tutor really helped me with my bio grades and I jumped from a D7 to A2! His lessons are very interactive and interesting and he gives out lots of freebies as well! 10/10 highly recommend"

"mr keefe is a very patient tutor who always gives detailed explanations whenever we ask questions, the student resources are very helpful as well and my grades really improved alot after i joined the tuition :) thank you for putting in so much effort in our lessons!!"
~Raicy [C5 to A2]
⭐⭐⭐⭐⭐
"The flashcards, I think they were really helpful. Since they were online also, on the way to school, instead of scrolling instagram I could just use them to revise bio because it’s very content heavy. Whenever I had any questions from the TYS or any practices that I did I would just send them to [Mr Keefe] and [he] would reply quickly and explain it quite comprehensively also…
Rather than just telling students the answer, he would try to help them derive the answer by themselves. Once at the consult someone had a question about codominance and [he] told them to think of an example, and find the answer that way… I think it was very worth it, I managed to improve a lot and get A1 for O levels, and also started liking bio again."
~Shivani [B4 to A1]
⭐⭐⭐⭐⭐
"I like how you talk to us as a friend, and also because you’re quite young so you’re not a dry texter. I also feel more comfortable sharing my doubts with you and clarifying everything, instead of asking a 50 year old teacher that may judge me if I have any weird questions. We can also relate to each other and you can give us life advice…
You can go for one lesson, just test it out. You’re not missing out on anything, in fact you’re missing out if you don’t join… It was one of the most enjoyable classes I’ve ever had, even though it’s a class setting."
~Giselle [A2 for Pure Bio]
⭐⭐⭐⭐⭐
"This person has been a student, and he knows what it’s like to be in the classroom, and he’s gone through the life stages that you have, so there’s some relatability that he would have…
He’s always there to help you if you need help, you just have to reach out and he will help you. It doesn’t just have to be about bio, it can be about something else that you’re stressed about… that’s like a very good support system in a stressful O level year."
~Sahanna [C5 to B3]
⭐⭐⭐⭐⭐
"I only joined thatbiotutor for a few months and managed to pull my score from constantly just passing at C6 to an A2 for olvls. Thatbiotutor has really helped me improve in biology to the point that i can teach my own friends when i was previously struggling. They have loads of resources to help you which is way more concise than the textbook and many memory shortcuts which are incredibly useful.
The lessons… are very engaging. Mr Keefe himself is also very energetic and willing to help and is somehow able to make tuition fun! i would definitely recommend struggling students taking pure bio to come try and attend thatbiotutor!"
~Frances [C6 to A2]
⭐⭐⭐⭐⭐
"Mr Keefe is always striving to help students as much as he can, so all his lessons and notes are also constantly improving. It will definitely help them a lot. Even though he is very young, it is still a very good tuition.
The way he always adds in fun acronyms to the keywords we have to memorise, it’s actually very helpful, and stood out to me a lot, because our teachers don’t usually do that. Overall, it was a good experience because the lessons were super helpful, it was really interesting, and it was really chill, at first I thought it was going to be stressful. When I think back about it, I’m very glad that I joined thatbiotutor."
~Xinqiao [A1 for Pure Bio]
⭐⭐⭐⭐⭐
"He will answer questions really fast, faster than my school teacher would. The way he answers is to the point, he’ll directly answer the question that I have, which gives me a better understanding of the bio content I struggled to understand…
If you are feeling skeptical but yet you want to join thatbiotutor, I would suggest you start out by attending the free [crash courses] that thatbiotutor offers. After that you can roughly make a decision on whether you want to join as a student, which I would highly recommend. I didn’t have any regrets joining."
~Jovita [B4 to B3]
⭐⭐⭐⭐⭐
"I actually have improved so much since I joined and I feel like ThatBioTutor has really helped me achieved my goals and honestly, i've realised that I have came a long way since the start of 2023. This has truly been an amazing experience. :)))"
~Lenel [E8 to B3]
⭐⭐⭐⭐⭐
"I actually look forward to the lessons, the free consults are nice also. Actually I think that you’re better than my school bio teacher… in your class you make effort to ask us questions, make us proactive, and make lessons interesting. I remember you had this Minecraft example, really enjoyed that a lot…
I think it’s really great, I improved a lot. After joining, I really had more interest in the subject, because I can study better, and do better in the subject. So I think it’s really good, I would recommend it to other people."
~Amelia [C6 to A2]
⭐⭐⭐⭐⭐
"Mr Keefe’s lessons were very helpful for me and it constantly gave me a push to review my mistakes and understand concepts properly. Not only that, they are engaging and due to his constant guidance, I was able to walk away with an A2 in O’lvs!!
The lessons are really fun and there are many free materials that we had access to that helped me further practise, and despite asking many questions outside of lesson hours, Mr Keefe was always patient and explained them to me. 100/10 would recommend!!!"
~Arpita [A2 for Pure Bio]
⭐⭐⭐⭐⭐
"My experience at ThatBioTutor has been fruitful and very enjoyable. Mr Keefe never fails to keep us engaged during the lessons, especially with the unique mnemonics he comes up with to help us better remember the details, which are extremely helpful for a content-heavy subject like biology !! Mr Keefe’s notes and materials are very well organised, which eases our learning tremendously.
It does not matter how strong your foundation is for the subject, as long as your determination to excel is there, together with Mr Keefe’s help, I believe every student will be able to achieve their desired grade!! Mr Keefe is a very patient and friendly teacher that will answer all your questions to the best of his ability, so do not be shy!!"
~Glendon [C6 to A2]
⭐⭐⭐⭐⭐
"I really enjoyed Mr keefes classes as they were very engaging and the memory hacks were very good. Mr Keefe also provided support outside of class in terms of educational career guidance counselling and was very keen to help us improve our bio. Overall a good experience"
~Shena [B4 to A2]
⭐⭐⭐⭐⭐
"Great tutor! He always goes the extra mile to support the student in their education in terms of resources and assistance. He is friendly and super approachable, hence I am always comfortable with asking him anything :)
He also hold surveys regularly to take in suggestions from students to improve his lessons further :) Overall, he is always on task and is a very diligent teacher, I am very lucky to have him as my tutor :D"

He helps students by providing a compilation of resources for effective revision and quality lessons with worksheets consisting of tricky questions to improve students’ understanding of various topics. He always clarifies students’ doubts and queries in a precise manner.
Not only is he willing to answer questions regarding biology, he also answers some questions regarding other aspects of school. I am very grateful to receive his aid to attain excellent results for biology. Thanks to him, my biology grade improved from a B4 to an A2, in the span of a semester."

"I'm quite surprised, like he will purposely buy and upgrade his equipment that he uses during tuition. Because like other teachers, they will use whatever they have. They won't try to make the class a better experience.
I feel that my experience is a 10/10 man… He is a very helpful teacher. He don't just read off notes, you know, he actually teaches."
~Emily [A1 for Pure Bio]
⭐⭐⭐⭐⭐
"5 star experience. Coz I actually did make an improvement, thanks to the notes and your teaching. I mean I wouldn't rate it a 5 star if I see no improvements. It's because I see the improvement, that's why I rate it a 5 star.
You taught me bio, I learn from you, I apply into my exams. I get my A1, I'm happy. I rate it a 5 star."
~Nathaniel [A1 for Pure Bio]
⭐⭐⭐⭐⭐
"Keefe is a very patient tutor who will take his time to explain a concept until you get it! I'm usually someone who has a lot of qns and doubts, so sometimes I'm worried abt spamming my teachers. However, he encourages me to ask as much qns until I understand.
Before joining, I was a bit lost as bio content can be quite heavy, but after joining, the resources provided really helped my reframe the way I approach this subject... If you're looking for an amazing bio tuition, TBT is highly recommended."
~Kaitlyn [A2 for Pure Bio]
⭐⭐⭐⭐⭐
"tbt really helped and changed my grades from a d7 to a stable A grade
he’s very consistent and precise when teaching, marking etc. the notes are also veryyyyyyyyy helpful for o levels because it really gives you the model answer that not only helps you understand but helps you answer those questions in exams. this gave me the confidence that i am capable of doing well in bio and also teach my friends how to do certain questions
tbt did a lot more than just improve my grades tbh he always advised and guided us in terms of our pathway into the future or just about the philosophy of life
each of these are very insightful because it reminds us that o levels is not the end point and there’s a lot more than that in life"
~Febella [A2 for Pure Bio]
⭐⭐⭐⭐⭐
"It is a very pleasant experience and it's really an eye-opener. Honestly, when I found out that you kind of like just graduated JC, I didn't have much expectations. I didn't actually think your lessons would be like helpful and stuff.
Then I came in, I was like, wow, this guy actually knows what he's doing. Taught me not to judge a book by its cover."
~Aspen [B4 to A1 in 4 months]

"amazing bio tuition with an incredible tutor! The notes are very helpful, especially the ready made quizzes that are easily accessible. ThatBioTutor really puts in the time and effort to help each and everyone of his students. The lessons are very engaging and really helped me to get a better grasp of each topic. They are also easy understand. I highly recommend his lessons!"
~Sharilyn [C6 to A1 in 3 months]

"This tuition is extremely good if you want concise pre-made notes which makes studying much more efficient and effective, combined with a patient teacher who goes above and beyond by taking the extra time to answer any questions that you have during and after class👍🏻👍🏻"
~Jessica [C6 to B3 in 2 months]
⭐⭐⭐⭐⭐
"The atmosphere is very easygoing, I don't feel pressured. I always thought tuition would be like, really stressful, then they ask you for due dates and everything for homework. But like it was more, easy going, like I felt more comfortable and I was kinda sad I didn't start the class earlier… If I was to recommend any of like my juniors to it, I would recommend you."
~Tania [B3 for Pure Bio]
⭐⭐⭐⭐⭐
"Patient tutor! Initially, I had my reservations about joining an online group tuition, as I was worried about its effectiveness for someone who was so easily distracted like me. However, after weeks of tuition with Mr Keefe, im glad to have joined his class as the lessons and resources he provides are indeed really useful!
Personally, it has made Bio a lot less daunting and im beginning to embrace Bio a lot more as a subject. The homework is also not too overwhelming! He has cleared many misconceptions students tend to have, so I really hope to see improvements in my upcoming Olevels!"
~Janine [D7 to B3 in 3 months]
⭐⭐⭐⭐⭐
"I definitely recommend this Bio tuition as the notes are not only comprehensive, the lessons are recorded which makes learning really convenient for me to refer to it any time! The lessons also has Kahoot which really tests us on the concepts & our speed in answering!"

~Tonee [B3 for Pure Bio]
⭐⭐⭐⭐⭐
"He's dedicated to providing his all for students and I feel his genuine care and concern for every student. He's definitely a teacher that knows what resources to provide to ensure excellent performance in every one of us. True to his words, he made Biology an easy and likeable subject. I saw real success in my Olevels and it was all thanks to him. You would definitely not be disappointed at TBT :)"
~Phyu Phyu [A2 for Pure Bio]
⭐⭐⭐⭐⭐
"I think the resources are very readily available, and it's very good quality. Everything is there when you need it you can just simply refer to it. Honestly, by myself, I wouldn't make my own flashcards. And I think flashcards, honestly, is a good way to revise. You can do it with your friends in free time, so it's very useful.
For some reason it's very motivating to attend. It makes me like bio more. Coz we pm (private message) you our answers, right? And it doesn't matter if it's wrong or not."
~Glenna [A2 for Pure Bio]
⭐⭐⭐⭐⭐
"His bio lessons are very interesting! Other than the content, I learnt bio-answering techniques that are not taught in class. During lessons, he would always encourage his students to answer questions and clear their doubts. He also checks on student's mental well-being and always encourages them to keep going. I really recommend going to his lessons!"
~Xinyu [B3 for Pure Bio]

"tutor was patient, classes were conducted in quite a private setting, so good for those who prefer asking questions privately! would recommend students to join!!"
~Xi Ning [C5 to A2 in 3 months]

"The last letter you sent us before O level, that one, it really motivated me a lot. Whenever I felt like, oh, I cannot lah, gonna give up already, I cannot. Then I just read that letter, be like, okay, I can do this, I can do this. It's just like, normal teachers, right? They won't really like put in that much efforts into motivating the students, ensuring that they're doing well."
~Le Min [A1 for Combined Bio]
⭐⭐⭐⭐⭐
"I would say that you are the type of teacher that gives a lot of hope on the students. And those questions that students have difficulties and they need help with it, but that you are always there to answer them."
~Jen Lin [B3 for Combined Bio]

"I think Mr Keefe is one of the best tutors in Singapore. He cares more about his students than the profits that he makes… If you're really struggling with bio, I think you're the best tutor out there and there's like no one better."
~Elena [A1 for Combined Bio]
⭐⭐⭐⭐⭐
"the notes given and aid provided was very helpful during my o levels, especially the suggested answers for common oeqs. mr keefe also helped to clear up many misconceptions I had during lessons and also outside of lessons. he is a very supportive tutor who helped me get from c5 for prelims to a1 for o levels. thank you mr keefe"

Student Stories!
"I didn’t know that the tuition would make flashcards for us, which was really beneficial for us to memorise content in a more effective way.
What I liked most is that it is online, which saves a lot of time from traveling. I also like that we can ask the tutor questions anytime, which is what I can’t do in school because the teachers are very busy."
~Jia Heng [B3 for Pure Bio]
⭐⭐⭐⭐⭐
"The tutor helped me a lot with answering my questions despite the time [constraints]… there was once near my exam and I knew I wouldn’t be able to ask my teacher because my school teachers are quite busy… having this allowed me to get help, and quick.
This tuition is online so you don’t have to travel… the environment is quite good as well, it’s not as competitive compared to being at a tuition centre."
~Agnes [C6 to B4 in 1 month]
⭐⭐⭐⭐⭐
"This tuition provides notes for every chapter and pretty it much summarizes everything. The flashcards provided helped me a lot with memorising, as well as the acronyms provided. I was able to use these techniques (flashcards + acronyms) for my other subjects as well.
The tutor records all lessons so if we missed out a point, we can rewatch and take it in, and even rewatch lessons that happened weeks ago."
~Nadya [A2 for N Level Combined Bio]
⭐⭐⭐⭐⭐
"He is a dedicated tutor that will patiently guide you through lessons and answer any questions or doubts you may have at any point in time... he teaches us answering techniques too instead of only content so that we can attain the highest possible marks in exams."
~Melissa [A2 for Pure Bio]
⭐⭐⭐⭐⭐
"The teacher is very encouraging and caring. Lessons are planned in an organised manner such that learning content and doing practice questions make it easier to understand the topics better."
~Shams [F9 to C6 for Pure Bio]
⭐⭐⭐⭐⭐
"He is a very approachable tutor and plays a big part in helping me comprehend all the topics that are taught very well... He teaches useful tips that allows me to remember points a lot more efficiently. Being very mindful, he pays special attention to every student and I find his guidance very helpful."
~Emelia [D7 to B3]
⭐⭐⭐⭐⭐
"I felt that online tuition would not benefit me, because it would be difficult to clarify my doubts (with the teacher) immediately. After joining, I realised I can use WhatsApp to ask questions, and if I see a question I really don't know, I can take a snapshot of it and send it to the teacher to ask about it, so it turned out to work very well.
I also like that our lessons are recorded… I can watch it many times if I want, and speed it up to 1.5x or 2x to save time. I like that classes are online, because travel time is a huge waste of time.
If there's a junior struggling with bio I recommend them to join this tuition, whether they're struggling with content knowledge or techniques to answer questions, this tuition covers them all.
~Jasmine [A2 for Pure Bio]
⭐⭐⭐⭐⭐
"This class is an all in one package, as the lessons are all recorded so you can always refer back for revision. There are also homework questions provided, and even if you can’t complete it due to commitments, the tutor is very understanding.
Whenever I have any doubts or misconceptions, he is able to answer them quickly, and he is also very patient and understanding. You don’t need to do notes and flashcards from scratch which helps to save time if time is not on your side and you need to do very quick revision."
