what subjects would I choose next year

I am really interested in science altough my marks for that is. not that good. I also like English and English is a must take subject. I want to aim for at least a double Science. I also thought of going to the same stream as my brother, triple science. but now I know that is not very possible for me at the moment by looking at my marks. but as the chinese people say, aim for the moon. if you fail to reach, at least you fall on the stars . I too believe in that. so I will aim for the best , if I fail to go there, I might get the second best
