IB Biology SL - Data-based Questions

These data-based questions are designed to help IB Biology Standard Level students practice analysing and interpreting scientific data in preparation for Paper 2. Each question focuses on key skills such as analysing results, performing calculations, and applying biological concepts. All questions are accompanied by sample answers and mark schemes, allowing you to sharpen your ability to confidently tackle data-focused problems.

Frequently Asked Questions

IB Biology Standard Level (SL) is one of the science courses introduced in the current IB Science curriculum (2016 - 2024). The Biology SL course is a traditional science course, whereby students develop a deep understanding of scientific concepts and solve both real and theoretical problems, with and without technology. The Biology SL course should be considered by students who are moderate to strong at science, and are interested in pursuing courses and pathways involving medicine, science, or engineering after their IB Diploma Program.

The IB Biology SL course consists of four assessment items that contribute to a student’s overall score for the course. There are three exam papers and an internally assessed independent investigation. Paper 1 consists of multiple-choice questions, Paper 2 consists of short-answer, extended response, and data-based questions, and Paper 3 consists of short-answer questions on practical experimentation, and short-answer questions from one option. The use of a calculator is prohibited for Paper 1, but permitted for Papers 2 and 3.

There are two phases students progress through in their two-year IB Biology SL course: the learning phase and the revision phase. The learning phase occurs in class, with their teacher and textbooks, where students first encounter and explore scientific concepts and consolidate their understanding by solving questions specific to that concept. The revision phase, which is what Revision Village is specifically designed for, is when students consolidate their understanding of all of the concepts in the Bio SL course and appreciate how the concepts are connected. In the revision phase, the most effective strategy is to practice lots of IB Biology SL exam questions to build confidence, reach mastery, and be prepared for the Biology SL examinations.

Revision Village is specifically designed to support IB students in the revision phase of their IB Biology Standard Level course. Revision Village has four main sections, each for different revision purposes: 1) Questionbank: a large library of IB Biology SL exam questions categorised by topic and ordered by difficulty, 2) Practice Exams: a carefully designed set of quizzes and mock papers for students to use in their final phase of revision, 3) Past Paper Video Solutions: step-by-step video tutorials of past Bio SL exam questions, taught by experienced IB Teachers, and 4) Key Concepts: short concise videos that recap the important theory in the Biology SL course. Revision Village is the perfect place for IB Students to learn, practice and prepare for their IB Biology exam stress-free, with all of the resources they need in one place.
