General ACCAPlease HELP! the best combination

i need advice on exam combinations. i will take my first exams this summer. is f7 and f8 a good combination to start? At university I've studied simmilar subject to f7, so the material is still a bit 'fresh'. f8 looks very hard as Im not a native english speaker. The worst thing is that both exams go one after another (wednesday and thursday). Or should I start with f4 and f6? there would be a 'break' between exams, but I've never studied law or tax before. And as I said I would prefer to take f7 exam as the material is still fresh. is it good to leave f5 and f9 exams for the last skills sitting? maybe I should start with f4 and f5, then f6 and f7, and then f8 and f9???? PLEASE HELP!
