Frequently Asked Questions
What is the IB Biology SL Questionbank?
The IB Biology Standard Level Questionbank is a comprehensive collection of IB Biology SL exam-style questions, organised by syllabus subtopic and concept, and sorted by question difficulty. Each question is accompanied by detailed, step-by-step mark schemes and video tutorials created by experienced IB Biology teachers. This resource is ideal for IB Biology SL students looking to practise exam-style questions on specific topics or concepts within their IB Biology Standard Level course, making it a perfect tool for focused exam revision.
Where should I start in the Biology SL Questionbank?
The IB Biology Standard Level Questionbank is designed to help students practise exam-style questions on specific topics or concepts within the Biology SL course. To get started, identify a concept you’d like to focus on and navigate to that section of the Biology SL Questionbank. For example, if you want to practise IB Biology SL style questions on Photosynthesis, you can go to Biology SL Theme C (Interaction and Interdependence), then select C1.3, which covers Photosynthesis. On this page there is a carefully designed set of IB Biology SL 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.
How should I use the Biology SL Questionbank?
The Biology Standard Level Questionbank is ideal for in-depth revision of specific topics or concepts. For instance, if you want to improve your understanding of the Diversity of Organisms, you can find over 20 IB Biology SL exam-style questions focused on this concept. Additionally, Revision Village offers an extensive library of Biology SL Practice Exams, where students can experience the length and difficulty of an actual IB exam using the Mock Exam sets. There are also Biology SL Key Concept videos, which allow students to learn and revise any underlying theory they may have missed or misunderstood in class.
What if I finish the Biology SL Questionbank?
With an extensive and ever-growing library of full-length IB Biology SL exam-style questions in the Biology Standard Level Questionbank, completing all of the questions would be a tremendous achievement, putting you in an excellent position for your final exams. If you were able to finish all the questions in the Questionbank, a great next step would be to head to the Biology SL Practice Exams section on Revision Village and challenge yourself with the Mock Exam Papers, simulating the length and difficulty of an actual IB Biology SL exam.
