Chemistry or Physics A-Levels?

For sixth form, I'm looking at taking chemistry/physics, history, maths and further maths, but can't decide whether to pick chemistry or physics! I'm wondering what both of the subjects are like, ie material, difficulty, revision (how much is needed), exams etc. If anyone could share their experiences, especially how they compare, that would be amazing! Thank you so much!

I’m starting Grade 13 this year, studying A-Level Maths, Physics, and Chemistry. I’ve already completed all my AS Level topics, and in 2026 I’ll be moving into the A2 content for all my subjects, with my final exams expected around October–November 2026. My goal is to achieve strong results — ideally A’s or even A* — and I’m highly motivated to stay consistent and disciplined. I’m looking for guidance on building a strong and effective revision or study timetable, along with the best study techniques, tips, and strategies to maximize retention and performance. I’m also curious about whether a retrospective or active recall timetable is effective... The one which is more effective , and I’d love advice on the most efficient study plan to help me stay organized and confident throughout the year.
