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

The website has been working great! Enjoying the quizzes and guides, couldn't be more thankful for such a resource.

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...

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

Inthinking Revision helped my kids greatly. They liked having the videos, notes, questions and solutions. Wonderful study material.
