Schools We Have Taught Students From:






Save The Planet With Us!
Up to 2025, ThatBioTutor donated a portion of its profits to global reforestation through TeamTrees.org in partnership with the Arbor Day Foundation, resulting in 1,982 trees planted. 🌲
From 2026 onwards, ThatBioTutor will be focusing our giving efforts on causes closer to home. 🇸🇬
Each year, our students will vote on the environmental cause on Giving.sg that matters most to them, and we’ll make a lump-sum donation to the chosen cause.

Quality Teaching Only
​Quality in teaching is our upmost priority, which we ensure in the following ways:
​
-
All tutors at TBT go through rigorous screening and testing that can take more than a month, before ever teaching their first formal class.
-
A tutors' coaching session is held weekly, where tutors are mentored by the founder (Mr Keefe).
-
Every single class ends with an after-lesson feedback form, for students to give feedback and point out any errors. During our weekly tutors' coaching session, we review and act upon the feedback weekly to make sure every class is better than the last.

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!
