The IB Biology HL Question bank is the perfect exam revision resource for IB students looking to practice IB Biology exam style questions in a particular topic or concept in their IB Biology Higher Level course.
Where should I start in the Biology HL Questionbank?
The IB Biology HL Questionbank is designed to help IB students practice Biology HL exam style questions in a specific topic or concept. Therefore, a good place to start is by identifying a concept that you would like to practice and improve in and go to that area of the Biology HL Question bank. For example, if you want to practice Biology HL exam style questions covering Cell Division, you can go to Biology HL Topic 1 (Cell Biology) and go to the Cell Division area of the question bank. On this page there is a carefully designed set of IB Biology HL exam style questions, progressing in order of difficulty from easiest to hardest. If you’re just getting started with your revision, you could start at the top of the page with the easiest questions, or if you already have some confidence, you could start at the medium difficulty questions and progress down.
How should I use the Biology HL Questionbank?
The Biology HL Questionbank is perfect for revising a particular topic or concept, in-depth. For example, if you wanted to improve your knowledge of Cell Division, there are over 20 IB Biology HL exam style questions focused specifically on this concept. Alternatively, Revision Village also has an extensive library of Biology HL Practice Exams, where students can simulate the length and difficulty of an IB exam with the Mock Exam sets, as well as Biology HL Key Concepts, where students can learn and revise the underlying theory, if missed or misunderstood in class.
What if I finish the Biology HL Questionbank?
With an extensive and growing library of full length IB Biology HL exam style questions in the Biology HL Question bank, finishing all of the questions would be a fantastic effort, and you will be in a great position for your final exams. If you were able to complete all the questions in the Biology HL Question bank, then a popular option would be to go to the Biology HL Practice Exams section on Revision Village and test yourself with the Mock Exam Papers, to simulate the length and difficulty of an actual IB Biology HL exam.
