When is the latest i should take my ACT?

<p>Hi, i am a junior and have already taken the ACT in April, but i was wondering if can i take it in September if i am planning on applying to U of M? When are you supposed to apply to college? Is that too late to take the ACT if i am already a junior? Thanks!</p>

<p>I'm a junior and i'm taking it in September so there's no worries i think :D
people usually apply novemberish for early decision but for regular timings, its USUALLY around decemberish that you apply</p>

<p>If you are trying to get into a relatively competetive school, you are going to want to be applying for an early decision. So if you're a senior next year, the latest you can take your ACT is in October</p>
