Is
790-Math level 2
780- chemistry
750- physics good enough for Cornell and how much value does SAT2 Have on your application
Those are plenty good for Cornell.
@Xzzzzhsh those are very good scores but have minimal impact. Without the rest of your profile what good is it for us to speculate your chances based on SAT II. My scores were only 730 and 680 for Math and Physics and I got in, but the rest of my stats and profile were much stronger and infinitely more important. The SAT II is only good for weeding out people on the bubble. For example, if you want to be an engineer but score a 550 in math, that would be bad, but a 670 or above says you grasp the concepts.
