You can get into the good courses in uni if you get As for the A
level subjects. Otherwise you prolly need to settle with the less
popular ones. Medicine, Dentistry,Law, Chemical engineering, all
these prolly you need a B3 at least to get in. Its wiser to work
hard for your GP because very often there are many students who get
straight As for their A level subjects. If you wanna compete with
top students for top courses in uni, its the GP grade that will
really determine whether you make the cut or not cos everyone else
applying will have straight As or close to that.
