Very useful for revision before tests. The sample questions are an effective practice.

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!

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...
