I just really love Biology and this site is amazing for me as it is so clear and easy to understand!

Very useful for revision before tests. The sample questions are an effective practice.

The Inthinking Biology website is very helpful in providing not only notes and diagrams to explain all the concepts, but also provides additional tests and Quizlets to strengthen your learning. I definitely recommend!

Dear Mr. Neil, This comes to appreciate your immense hard work in creating, collating and compiling all of these very relevant, well-timed resources in lucid, friendly language for all IBDP students and facilitators as well. Gratitude and thanks! Seethalakshmi S

Inthinking Revision is a very helpful website for IB students. I highly recommend it for review and teaching classes. 10/10. Amazing job StudyIB creators!

The website is a blessing. I'm so happy to have stumbled upon it and I recommend it to anyone who is preparing for the SL math exam. The videos have been so successful in helping me recall content from the years... The website works very well and the note sheets, quizzes, and exam styled questions...
