What Students Are Saying About ThatBioTutor:

★★★★★
E8 → A1 in 3 months
"Unlike school teachers who just merely read off the slides, these tutors had somehow made such a content heavy subject into something engaging... The night before bio O-levels, they were all staying up till midnight to answer their students' questions... it really showed how much they care for their students."
Yong Zheng, Sec 4 in 2024

★★★★★
F9 → A1
"After using TBT's notes and memorising all the shortcuts I managed to get the model
template answer and memorise it easily... TBT is a really good option because I joined and I managed to get from a failing student to an A1 student."
Gwen, Sec 4 in 2024

★★★★★
C6 → A2
"Excellent tutor in terms of the amount of resources he has... 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 (my Sec 3 EOY grade) to A2 in O Level 🙏"

Frequently Asked Questions
Q: Do you teach physical lessons?
+
Yes! Starting 2024, you choose between coming online or physically.
Q: Other than weekly lessons, what are the other perks of being a student here?
+
There are a plethora of benefits, including notes, flashcards, lesson clips, extra practice papers, 24/7 whatsapp help, snacks when you come for physical lessons... just to name a few!
All these extra perks and resources are free of charge for our students. For more details please watch the video here.
Q: Do I need to turn on my mic/camera during online lessons?
+
It is not compulsory, though we encourage students to respond to questions their tutor poses to the class via the zoom chat!
Q: Is there a lot of homework?
+
The weekly homework consists of a few questions, and is highly manageable (We don't believe in overloading students with homework when they already have enough from school).
Homework is also not compulsory to do, although if you do it, you can claim Homework Points for rewards! (e.g. Bubble Tea, Starbucks Gift Card)
Q: How many students are there in a class?
+
The cap for physical class will be around 20-25 students. Don't be daunted by the numbers, try it out yourself in a trial lesson, and see why so many students still love our classes.
Q: What levels do you teach?
+
We teach only O Level Pure/G3 Biology, so we can truly specialise and develop the best lessons, teaching methods and resources for our students.
Sec 3s, classes open for you March of each year!
Q: Do you teach combined bio?
+
At the moment, only Pure Bio.
Q: Do you teach 1-1 tuition?
+
Unfortunately, we have too many students to afford the time to teach 1-1. Good news: Our students can ask us questions 1-1 on WhatsApp, 24/7!
Q: But what if I can’t ask all the questions I want in a group class?
+
Our students never face this problem because they can ask questions 24/7 on WhatsApp.
We even take the time to voice message them explanations if the question is more complex.
Q: Are all the classes taught by Mr Keefe?
+
No, as we have a small and elite team of tutors who each take classes of their own.
Rest assured that no matter which timeslot you go to, the content and methods taught is the same across tutors, as we standardise it for every lesson.
Q: Can I try just one lesson?
+
Yes! To request for a trial lesson, drop us a WhatsApp message— one of our friendly staff will respond ASAP!
Q: Can I know more about the class fees and lesson timeslots?
+
Because we offer several class options tailored to different needs, fees may vary.
Our team will also provide the most updated timeslot availability through WhatsApp.
To know more, drop us a message — one of our friendly staff will respond ASAP!
