I've been told that Cambridge likes law applicants to have studied Maths A level. Your GCSEs are relatively weak for a Cambridge application - sticking with 4 AS subjects would help to counteract that, IF you can get an A in Maths.
Not at all
The narrative that you need straight A* at GCSE to get into Oxbridge is untrue; only for Medicine, really.
3 AS is fine, having 4 won't give you any advantage, and it's probably better to have 3 extremely strong a levels than 4 relatively weaker ones. Many schools only offer 3, as was said earlier in the thread. I personally only do 3 and don't think it'll put me at any disadvantage.
Ok, so if that graph is accurate then they are average.
It comes from a Cambridge admissions tutor, so I should hope it is accurate. That being said, GCSE's are only 1 factor in the whole application, there are a lot more important factors, hence the range.
I'm going to apply to Cambridge for law next year but I only do 3 A levels (inc. history). I have decent GCSE grades too. Do I stand a good chance of at least getting an interview?
