Should I send scores that aren't required?

I got a 1420/1600 on the SAT and a 32/36 on the ACT. Since the schools I’m applying to require either SAT and 2 subject tests or the ACT alone, I am sending my ACT. Should I also send my SAT though since it isn’t so bad? And for the schools that require all scores to be sent, I am wondering if my SAT scores will look good since I got a 1390 and 1420 while I got a 29 and 32 on my ACT.

I think you should look at how you did percentile-wise. If they are good and similar, send both if it doesn’t cost too much.

30 points isn’t a significant discrepancy – send them.
