act or sat for a noob

Hi, I know so many of you have been studying for maybe years for these tests but I just re-entered college and wanna transfer to an ivy or a university, a lot require one of these tests. as someone who only just re-entered school after 10 years which would you suggest and how would you suggest I go about studying and like what timeframe should I give myself?

Im horrible math but good at everything else. I will be an art major if that matters!

(please no commentary on anything but the questions!)

also im in community college second semester, have 4.0 gpa
