Frequently Asked Questions

Is Combined Science (0653) easier than Co-ordinated Science (0654)?expand_more
Combined Science covers less content (single award) compared to Co-ordinated (double award). It is often considered lighter in workload, but the conceptual difficulty of the topics remains the same.
Do I need to take the practical exam?expand_more
Yes, the practical assessment accounts for 20% of your grade. However, you can choose between Paper 5 (Practical Test) where you do experiments, or Paper 6 (Alternative to Practical) which is a written paper about experiments. Most private candidates choose Paper 6.
Can I move from Core to Extended?expand_more
Absolutely. We often start students with Core concepts to build confidence. Once they are scoring consistently high, we bridge the gap to Extended content to aim for A-A* grades.
How is Times Edu different from standard tuition?expand_more
We don’t just “reteach” the textbook. We focus on “exam engineering”—teaching you exactly what the mark scheme requires, how to avoid traps, and how to maximize marks per minute.
