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

Dear Mr. Neil, This comes to appreciate your immense hard work in creating, collating and compiling all of these very relevant, well-timed resources in lucid, friendly language for all IBDP students and facilitators as well. Gratitude and thanks! Seethalakshmi S

The site is great for revising the basic understandings of each topic quickly. Especially since you are able to test yourself at the end of each page and easily see where you need to improve.

My students love the website, I am using it for revising all the topics.

I just really love Biology and this site is amazing for me as it is so clear and easy to understand!

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