I take the ACT test again?
ok, I wonder if I should take the ACT again the first time I took it, I have a 30 … is that a score as good enough for schools like USC, UCLA, UCI, UC Berkeley, Cornell? Or should I take the exam again? I will not have much time to study, it has perhaps time to take 1 or 2 more practice tests … the ACT test can improve, or is the type of test that a little stay in the same range of score … I've heard evidence do you already know … so I take it again? thank you for all your advice! 
What I heard is right: things ACT tests you already know and can not really improve your score unless you do by accident. I would not take it again if I were you. Apply to the universities and I am sure that they accept at least one with a 30 on the ACT.
