2220 SAT vs 33 ACT + additional question

Which should I submit?
SAT 2220
-CR 740
-Math 690
-Writing 790

ACT 33
-English 36
-Math 26
-Reading 36
-Science 33

My other question is, how much does my low math score impact my composite? If I improved that to 30, would my composite be closer to a 36?

edit: Math is not my strong suit, by the way, so I’m not sure how much I will be able to improve.

No, math is not your strong suit. The composite is literally the average of the subscores. If the 26 changes to a 30 your average will be a 34. A 4 point jump would be a big jump. The SAT looks a little bit better right now. https://www.tntech.edu/admissions/actsat

Wow, yeah I didn’t realize. I have no experience with the ACT. I’ll be taking it again at the end of this month, hopefully I can get those 4 points.
