You have finished your GCSEs, you have chosen your A Levels, and you have a long summer in front of you. Here is the good news: you do not need to study all summer. As a science teacher of more than 25 years, I can tell you that the students who start Year 12 strongest did a small number of specific things, not a mountain of general ones. This is the list.
1. Secure the GCSE foundations that A Level assumes
A Level teachers will assume your GCSE core is solid and move fast. For chemistry that means moles, balancing equations and calculation confidence. For biology it means cells, transport and the core practical skills. For physics it means rearranging equations and units. An hour or two a week is plenty. My free walkthroughs on the Advisory Science YouTube channel cover whole GCSE papers in about 30 minutes each, and they are the fastest audit of what you actually remember.
2. Set up a note system before week one
A Level buries students who "sort their notes later". Decide now: one folder or notebook per subject, notes reviewed at the end of each week, and a running list of anything you did not understand. The students who do this from day one never need to catch up, because they never fall behind.
3. Read and watch ahead, lightly
You do not need the textbook in July. Watching a few videos on the first topics (cell structure for biology, atomic structure for chemistry, mechanics for physics) means week one feels like revision instead of brand new material. Light familiarity beats heavy pre-study every time.
4. Practise on real questions from the start
The single habit I drill into every tutee: whatever you learn, test it against real exam questions the same week. It is how my GCSE students improve by two grades on average, and it matters even more at A Level, where the questions are designed to make you apply ideas in unfamiliar contexts.
Coming soon: A Level lessons and tuition
I am launching A Level Biology, Chemistry and Physics tuition, along with complete, ready-to-use A Level lessons in the Advisory Science store, so if you want structured support through Year 12, keep an eye on the site. In the meantime, one-to-one science tuition is available now, friendly and patient, with an enhanced DBS check and a feedback note after every session.
If you are still weighing up which sciences to take, see what grades sixth forms actually ask for, and how much harder A Level really is compared to GCSE
Starting A Levels in September? Which subjects did you pick? Tell me in the comments, and if there is a topic you are nervous about, say so, I will point you to the right free resource.
