<p>Naturally a 35(which is equiv. to a ~1580) will help your admission... you don't have to submit your SATs if they are lower than your ACTs, but what makes you think that you would do so much better on the ACT than you did on the SAT? ACT is easier(I think, some others don't though), but you are give alot LESS time than on the SATs...</p>
<p>Give it a try and see how you do but if you are a senior, you're running out of time! Good luck!</p>
<p>Princeton only accepts the ACT under certain conditions...it isn't really an option that people usually take. Did you study for the SAT I? Get a practice book, study like crazy, and sign up for the last test date.</p>
<p>Oh, and are you an athlete? If you're recruited, that's okay, but if you're trying to get in on strength of academics, you'll need to pull that up a little (unless you've done some massive research at a university or published a book or something).</p>
