3 Sciences and Maths Watch
I suggest you do a non-science subject, just to give you a break from all the sciency stuff. But that's just my opinion
I was looking at English Literature to have one subject a bit different to all the sciences...but also because I really enjoy it and find it interesting!
Medicine is an option for the future but I am not really sure, it is the only reason that I would take Chemistry. I find Physics FAR more interesting and easier, Chemistry just seems to be learning exactly what every element does, but I dont know if this changes much at AS.
Im doing 3 sciences and maths, and its fine. Its perfect if you want to do medicine (like me) or other science related things. If you do take it up and find it boring, then maybe youre just in the wrong line of subjects. I personally find it fine, but cant wait until i start doing medicine
Btw at my chem interview at Oxford last month i didn't come across any other applicant doing my A-levels, let alone 3 sciences with maths. Bit strange eh?
For medicine, Cambridge loves this combination, while UCL/Wales/etc give preference to a non-science subject at AS/A level. Physics isn't that useful for medicine if you're doing maths, so pick the one you love and will therefore do best in.
Physics vs. Chemistry- I'd vote Chem., but you need to think whether you might want to do engineering etc.
It sounds as though you don't like Eng. Lit. particularly. Don't force your way through if that's the case- do 3 sciences and maths- and enjoy it. If you do choose medicine, you can just not apply to uni's which don't like this combination (and there's not that many).
