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.

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

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...

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

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

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.
