Didn't mention A-level in personal statement

I've finished with my personal statement and cut it down to exactly 47 lines. However, I realised I didn't mention anything about the A-level subject im currently studying, is that ok or should I try free up even more space to write about the A-levels.

They know the A level subjects your studying, so there's no need to talk about these in your personal statement. As long as you've talked about your passion for the university course you want to take, then you're fine.
