Should I take the ACT again?

I was really hoping for a 34, but got a 33 instead.

English:30
Math:36
Reading:32
Science:35

I was essentially one question away from a 34 (got 33.25), so is it worth it to take it again? I myself am reluctant to because I feel I have completely peaked at Math and Science. I want to apply to UCLA or USC.

I would not take it again because you may not do as well in math and achieving a 36 is very impressive. Unless you are willing to study a lot, I would keep the 33.

No school will reject you with a 33 but accept you with a 34. Your efforts would be better put elsewhere.
