<p>OK here's my opinion, I didn't read every post though. If you take the SAT and do extremely well (like you don't think you can do better on the ACT), submitting high ACT scores in addition to them would not help you. I think it would make you look a little silly to the colleges if you like got a 1600/2400 and then took ACTs...now if you think you can improve your score, by all means retake and try ACTs, and then it's fine to send both scores.</p>
<p>As for SATIIs, most schools only look at the highest 2 or 3. So you can take a bunch of them untill you get an 800 on 3 of them. Past that, there is not point.</p>
