SAT I or SAT II? Early Decision/Action!

<p>I need to take one more SAT II and I plan to apply early action/decision to some schools (Cornell, Carnegie Mellon, Columbia, Johns Hopkins) . My SAT I is about 2200 but I have not taken SAT Math II yet (necessary because I plan to do engineering). Is it okay to take the SAT II in November and try the SAT I again to boost my score about 50-100 points?</p>

<p>OR should I just take SAT Math II in October and SAT I in November?
Would both tests count either way for EARLY ACTION/DECISION? THANK YOU!</p>
