Hi,
So I’ve taken the SAT and the ACT once each. My SAT score was significantly lower than my ACT score. I got a 1500 on the SAT (740 on math, 760 on English) and I got a 35 composite on the ACT (36 math, 35 both English, 32 science). I wasn’t happy with my writing scores on either test. I’ve only had two subject test scores that I’m happy with: 750 math 2, 750 Chem. I’m trying to decide if I should retake my SAT. As a person who wants to go into biomedical informatics, should I retake the SAT and focus on getting a higher math score and writing score? Should I retake the ACT and focus on getting a higher science score and writing score? Should I just stick with my current test scores and submit only the ACT? Any and all advice is appreciated! Thank you 
You have great ACT score, so go with that.
Keep the ACT score, colleges don’t care about the essays portion too much I’ve heard.
Your test scores are fine. The ACT is better than the SAT, though.
