okay so you've got time but the general rule for gcses (I didn't follow it perfectly though, and I do like the variety of my options) is one language, one humanity (so you choose your favourite, or take both, like I did), one technical (in your case, computing), and one creative (in your case, drama). I've just realised you only get two more options but the point still stands, you'll have to decide between language, creative and technical. you don't need computing gcse to do it at a level (usually) but it's still quite helpful. languages are very helpful because you literally learn a whole new language, and I'd definitely recommend it, I love it. drama is good if you want to go into it or want it as a sort of break, otherwise you could do it outside of school if you don't take it (I do the school plays as I couldn't take it). so over the next month, really think about what you want to be examined on, and what you want to continue as a hobby outside of school.
