KS3 Science combines three disciplines — Biology, Chemistry and Physics — with a practical focus on Working Scientifically. Understanding cells, chemical reactions, forces and experimental design prepares you for the rigour of GCSE Science.
KODO covers all four strands with questions that test conceptual understanding, not just memorisation. Each question includes a detailed explanation so you learn from every answer.

Why Revise Science?
- Science is compulsory at GCSE — you'll take either Combined or Triple Science.
- KS3 topics like cells, particles, and forces are directly examined at GCSE.
- Practical skills (variables, fair testing, graph interpretation) are assessed in exams.
- Scientific literacy helps you understand health, technology and environmental issues.
Exam Tips for Science
Learn key definitions precisely — examiners look for specific terminology.
For 'explain' questions, give the cause AND the effect.
In calculations, always show your formula, substitution, and answer with units.
Draw diagrams clearly and label them — this can earn marks even if your written answer is incomplete.
