Those are great subjects for keeping your options open, but it really depends on whether you think you can get the grades. If maths or physics bored you or if you just don't learn in ways that allow you to do well in those subjects they're not a good idea. All your options are intense, so make sure you've thought it through. But if you can do it, uni's love subjects like that! So that's great if you don't know where you're going after this yet.
If you have some idea of what you want to do after A-Levels (job or uni wise) try to factor that in. Make sure at least one of your subjects is relevant to your career path and make sure that the uni courses you might take will accept those A-Levels. That's not me saying if you want to be a manager you should do business. Actually English would be great for that since it shows communication, understanding and literacy. What I'm saying is, you're probably fine, your subjects give a wide range, but try to think about it more than what subjects you should like and more of what you'd like to do with your life.
And don't worry about not being sure, I've worried about mine for ages! I did loads of research and stressed way too much. Try not to go there. As long as you can handle your choices, you like them, and it'll get you where you want to go, you'll be fine. Good luck!
