IB Physics SL question bank

Exam-style practice for IB Diploma Physics at Standard Level, first assessment 2025. Every SL sub-topic from A.1 Kinematics to E.5 Fusion and stars has its own page of original questions, written in the style of the current papers: Paper 1A multiple choice, Paper 1B data-based questions and Paper 2 short-answer and extended-response questions.

Each question comes with a full, original mark scheme in exam style: one mark per point, error carried forward, accepted ranges and the alternative routes that also earn credit. Multiple-choice questions explain every option, so you see exactly which mistake leads to each wrong answer. Tick questions on any page to build and print your own practice test.
