It has really a lot of tips to prepare IB students for the exams, as well as exercises and guidance. It gives a clear outline of all knowledge we need to complete them appropriately.

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!

I love this site, it is so helpful in making sure the content is both comprehensive but easily understandable.

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

The site helps me with my revision, and it makes me confident for my exams!

Really great website, tutorials are easy to follow and split topics up into sections that are manageable. This makes revision easy to track and the test questions provide accurate indicators of progress to make sure material has been learnt.
