The IB Biology Higher Level Questionbank is designed to help students practise exam-style questions on specific topics or concepts within the Biology HL course.

On this page there is a carefully designed set of IB Biology HL exam style questions, arranged in increasing order of difficulty. If you’re just beginning your revision, you can start with the easiest questions at the top, or if you’re already confident, you can dive into the medium-difficulty questions and work your way down.

For instance, if you wanted to improve your understanding of the Diversity of Organisms, you can find over 20 IB Biology HL exam-style questions focused on this concept. Additionally, Revision Village offers an extensive library of Biology HL Practice Exams, where students can experience the length and difficulty of an actual IB exam using the Mock Exam sets.
