how cooked am i for a levels on a scale of 1-10?

I picked English Lit, Media BTEC, French & Theology for my a level options. I've already accepted that I'm gonna be homeless but I'm actually kinda good at these subjects except for media cause I don't do it. Last year for Y10 mocks, I got 7s in English and French, 8 in RE(but I don't really need it) and a 6 in history so I think I'm fine with actually doing them. But everyone I know says that I shouldn't pick 4 or that I should pick film instead of media and I should do music since I did it for GCSE. So how hard is theology and french because they're the only ones I'm really worried about. People say that they're both nothing like GCSE so should I do both knowing that I might struggle?
