Chem retake?

<p>I took the chem sat in june and got a 730. I realize that it's not that horrendous of a score but I feel like i wasn't prepared and could do a lot better. The questions is though, is it really necessary to retake it in october again?
BTW i'm interested in duke, mcgill, university of toronto, cornell, brown and university of chicago. I am a canadian citizen living in the US on my dad's working visa, not really sure if i'm international of not.</p>

<p>Oh and I’m out of practice tests, so my only option would be to just go through them again</p>

<p>For Cornell/Duke, etc. yes, you should aim 760+ on Chem…I got a 750 on the same test this June, and since I’m taking AP Chem next year, I will for sure retake.</p>

<p>good luck bro</p>

<p>thanks man i have decided that theres no harm in retaking so im going for it. good luck to you too</p>
