Following on from my last post... the poll just added is useless - you need advice on what you need and tips on how to shape your A-levels for either career. I'm sure you won't be waiting until one subject has the clear lead of votes to drop it!
For medicine at Cambridge, you really need 3 science/maths A Levels, whereas for Law there are no specified subjects.
So drop one of history/english.
maths is not essential for medicine, no universities explicity require it. You needs maths to do medicine, generally speaking, but it's taught during your degree, in the early stages. So if you do maths, it will be easier, but not a must
Take one off maths...
Sorry for the mistake!
i wouldn't get rid of maths at all if i were you. looks good for law and medicine. you only need one essay subject for law if any, i know someone that got into oxford to study law who did science a levels. as long as you get the grades you'll be fine.
also can i just say that if you did maths and english together unis would love you and want to grab you.
For law, top unis don't mind if you have mainly science subjects because when it comes to entrance tests and interviews they will be testing your aptitude for the course.
By dropping history, you have all the requirements for studying medicine and the english creates a brilliant contrast. Also, maths is an indispensible subject when it comes to Oxbridge.
Have you also considered the possbility of starting with 5 AS?
