Would a 720 in the SAT Math II hurt my chances at the top schools?
No. That’s a decent score. Why would it hurt?
If you think you can do better a second time, I would recommend doing so. I got a 730 my first time but knew I could do better, so I prepped some more and got a 790.
Honestly, if you are hoping to go into any sort of mathematical or engineering program that may not look great. Just my opinion though. I think most people would say that a 720 won’t exactly help or hurt you chances though.
@starforward it’s a fine score. Mind chancing me? http://talk.collegeconfidential.com/what-my-chances/1908636-what-are-my-reaches-and-matches.html#latest
