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

StudyIB chemistry is an amazing resource. I like that it is condensed but also informative; I much prefer it to the textbooks! I only used StudyIB notes for my mocks and am also planning on using it for my final exams. I really recommend it!

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!

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

This is genuinely the holy grail of IB chemistry resources. IB is very stressful and keeping on top of your content and revision is difficult. This website has amazingly clear explanations for all syllabus points, it's so good that I haven't use my actual notes for revision. The multiple-choice question...

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!
