I'd drop it if it's getting boring. Doing 4 A2s is a lot of work and requires a lot of motivation even if you enjoy all your subjects. If you don't, it'll be much harder to force yourself to put the work in, and as the above poster mentioned, there's always a chance you'll get an offer based on all 4 subjects. 3 A-levels and an AS (or in your case, 3 A-levels and 2 ASs) is plenty even for Oxbridge, and for English or history, wider reading would be much more beneficial to your application than A-level maths.
In my opinion, I think you should give it up and focus on extra reading. You will have less schoolwork, which will be an advantage before both the interview (more time for extra reading- I know I would have appreciated having less homework and coursework that week, when all I wanted to do was read) and before exams. If you are confident you can get AAAA, go for it, but don't do it simply for Cambridge and bore yourself to death for a year.
I did 4 A-levels: History, Geography, Chemsitry and Latin. My offer specified I had to get As in History and Latin, plus one other subject. They blatantly weren't fussed about Chem, but couldn't actually say it. I dunno if it was an advantage, but the only reason I did it was cos I was interested in Chemistry. If you aren't too bothered, drop the other subject and do more reading.
The only argument against what most of the people have been saying is that it could help your application slightly, when i was in your position i probably would have kept it ,.. ie anything to improve my chance slightly, but it is a lot of work and for most, if not all colleges it wont make a difference!!
a) they will not give you offer based on 4 a-levels with 99% certainty..more and above, they would be very likely to exclude maths form your offer
b) improve your application? not at all, I would say
c) if you feel you would rather drop it, definitely go for it - for subjects like english having maths will not help your chances, and if you are doing AS maths, you can easily calculate how much time will you be able to devote to further reading and thinking about your subject and what you read having dropped A2 maths.
It depends how you think it will affect you if you decide to carry on with maths. If it might affect how you do in other subjects, it's not worth it. If you're confident to carry it on, though, it certainly won't hurt to have an extra A level, and while it's not much use for History or English degrees, it's different to your others subjects and so demonstrates that you have a good range of academic skills. Since maths is a "hard" A level, it's going to be a bonus even if it's not involved in your degree course.
If you want to carry on with all four and you can get four As, then by all means carry on with the four. But it sounds to me like you're not really that keen - in which case I'd drop Maths. Why make your last year at school uncomfortable for yourself? Cambridge won't care: maths is unrelated to your course and they have a big thing about making sure people with 3 A levels aren't disadvantaged (and Geoff Parks recently had a big rant that people are taking too many). So really don't take it just for the sake of Cambridge! However, as other people have touched on, maths A level may make you more employable in future.
It really has to come down to what you want to do!
I emailed Cambridge about a week ago, because I wanted to know whether it would be preferable to do 3 or 4 A Levels for A2. They said that 3 was fine, and they did not discrimate between people who had 3 or 4.
I forgot to add also that maybe taking AEAs in the relevant subject(s) would be more useful.
hey I was in a similar situation also, had 4 a levels and had applied for music at cambridge. prior to the interview I dropped one of my subjects as it was unrelated, so as I could concentrate on music, as I have other exams outside of the A level course to prepare for in relation to it and felt that it would benefit me more. I explained all this to them and in the end was given an offer so obviously not having 4 makes no difference! In the end they want to see dedication to the subject you have chosen and if you drop an unrelated subject so you are able to put your efforts into the subject you wish to read at Cambridge then you cannot be at a disadvantage! xx hope this has helped
I'm doing Biology, Chemistry, Maths + Further Maths and Physics at AS at the moment (doing A2 maths this year), and I've been advised not to drop any subjects for next year at least until I've applied to Cam and got an offer or not - if I get an offer then I'll be asking to see if I can drop Bio. Sounds like I'm gonna enjoy next year :s
