<p>No. There isn't an advantage but send the better score--and ignore the worse score. In this case, don't send your SAT.</p>
<p>The main advantage of the ACT at most colleges is that you don't need to take SAT IIs if you take the ACT with Writing. But I don't know about Harvard's requirements.</p>
<p>But like I feel like If I apply to a nice college, they will see that oh he got a 33 for example, why didnt he take the SAT. Of course act is much easier, but I feel like they would rather choose the SAT over ACT, regarding difficulty levels</p>
<p>I doubt it. There's no clear "SAT is better than the ACT" mentality. It's a choice that you can make. They won't hold it against you that you didn't submit SATs. You could always submit ACT and SATs (as I did) but it's really up to you.</p>
