<p>You can take either ACT or SAT I. </p>
<p>Top colleges like Ivies, MIT, Caltech, CMU, michigan etc and many others require SAT II in 2 subjects. Some do not require but still “recomend” SAT II. </p>
<p>But if you are good at maths and science as you claimed earlier, then SAT IIs are not difficult(maths and science tests). So no need to worry!</p>
<p>Make a list of colleges of your choice(12-15), and see which of them require you to take SAT II.</p>
