If you are choosing sixth form courses, or you are a parent trying to make sense of the entry requirements, this is the guide I wish every family had. I have spent over 25 years teaching science and I was a vice principal, so I have sat on both sides of the enrolment table. Here is what the grades mean, what sixth forms actually ask for, and how GCSE grades translate to A Level.
Typical entry requirements for A Level sciences
Most sixth forms ask for a grade 6 or 7 in the science you want to study, and many also want at least a 6 in maths for chemistry and physics, because both lean on calculation from week one. Requirements genuinely vary between schools and colleges, so always check the specific sixth form's published criteria rather than a general list.
Can you do A Level sciences with Combined Science?
Usually yes. Most sixth forms accept Combined Science at around 6-6 or above for a science A Level, sometimes with a maths condition. Triple Science is helpful preparation but it is not a requirement at most places, and I have taught plenty of Combined students who outperformed Triple students at A Level.
Do GCSE grades predict A Level success?
Only partly. A grade 8 student with poor habits can struggle, and a grade 6 student who reviews weekly, practises real questions and asks for help early can thrive. What GCSE grades really measure is your starting point. The gap between GCSE and A Level is bridged by method, not by talent, which is exactly why the right support in Year 12 matters so much.
Choosing your A Level science combinations
Work backwards from the destination. Medicine, dentistry and most bioscience degrees want chemistry, usually with biology. Engineering and physical sciences want physics and maths. If you are keeping options open, chemistry is the science that unlocks the most doors, paired with biology or maths. And if you are unsure, pick the subjects you genuinely like, because two years is a long time to study something you dread.
If results day does not go to plan
Entry requirements are not always final. Sixth forms often show flexibility on one grade, especially if you can show commitment, and there are resit routes too. I have written a full guide for parents on what happens if GCSE science does not go to plan.
Start Year 12 strong
I am launching A Level Biology, Chemistry and Physics tuition soon, plus complete A Level lessons in the Advisory Science store. Until then, the free paper walkthroughs on the Advisory Science YouTube channel are the quickest way to make sure the GCSE foundations are solid, and one-to-one science tuition is available now.
Once you have settled on subjects, see how to spend the summer before Year 12 begins, and how much harder A Level actually feels compared to GCSE
What are your sixth form's entry requirements, and are you on track for them? Ask in the comments and I will give you a straight answer.
