My teacher recommended Inthinking Revision for our class and in my opinion it was a really useful site in preparation for unit tests, exams, and to get a sense of understanding of my math level. What was really helpful was the self-evaluation button and the notes section, as it gave me a sense of understanding...

This site has helped me improve in Physics as to take the exam. The best part is that it takes you through each step of the problems and gives you worked answers in a way you learn from your mistakes, instead of being left in the dark. It helps a lot for studying.

The videos about the concepts along with the revision notes made it really easy to recall the material....so thank you!

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

StudyIB is life changing! The best resource out there. StudyIB should, and will, be a staple in every IB chemist's revision!

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.
