<p>It certainly won’t help your chances, and yes, it will make getting accepted more difficult, but certainly not impossible. I’m a junior who took the SAT in May and I scored a 1660, so I’m in a similar situation. I’m buying the Collegeboard SAT Blue Book, and I recommend you doing the same and studying during the summer. You didn’t say whether you’re a sophomore or a junior, but if you’re a junior like me, the October SAT is pretty much the last chance we have.
Good luck!</p>
