A level subjects

Can i still get into Cambridge uni and to study law if i do maths economics and art for a levels and get a* in all? Or would i be less likely because i need another written subject such as phsycology or eng instead of art?
I rlly need help, school starts in a few days but idk if my subjects are fine. Shall i change the art for smth else but i got a 9 in gcse?

I had a quick look at the Cambridge website and it says that no specific subjects required by any Colleges, but it also says useful preparation would be doing English (either lit or lang), history or a language. I hope this helps
