Is it too late to take the ACT?

Hi! I’m an upcoming senior who took the ACT only once in June. I scored a 25 (really bad, I know) and I’m hoping to get a 30. I was gonna sign up for the September ACT but there aren’t any test centers near me. I signed up for the October ACT, but I’m afraid if I don’t like my score. Will December be too late to take the ACT? Here are some of the colleges on my list:
Cornell
Northeastern
Binghamton
Stonybrook
Colgate
Queens
Baruch

Will December be too late to take the ACT?

Can you get a stand-by ticket near you at the September sitting of the ACT?

Have you considered SAT?

December may or may not be too late depending on the college/university. I wouldn’t want to have to count on that.
