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!

The Maths AA HL course on Inthinking Revision has been of tremendous help to me, especially with the way each section is structured, usually consisting of videos and revision notes, followed by quizzes to practice your skills before jumping into exam-style questions, which are arranged in ascending...

Thanks for this great initiative. I like how the site is broken down and explained in different assessment areas.

It is life saving... I am passing IB because of this site!

I found your website really helpful and I enjoyed using it.

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