I am applying to highly competitive bioengineering/chem. engineering programs at UIUC (choice #1), Purdue, University of Minnesota. I am also applying to BS/MD programs such as Northwestern HPME, Case Western PPSP, and UIC GPPA. Although most of the schools I am applying to do not REQUIRE the essay, some do recommend it, and I am not sure about the trade-off between submitting a much worse SAT essay compared to a worse ACT science.
ACT: 35
-English: 36
-Math: 35
-Reading: 35
-Science: 33
-Writing: 11/10/11/11
SAT: 1570
-Math: 790
-English: 780
-Writing: 6/5/7
Given that I am applying to highly competitive, science-focused programs, I am unsure on whether to send my ACT with a much better essay but worse science or my SAT with a worse essay and a great overall score.
Any help would be greatly appreciated. If it is relevant, I have three recommenders: French, math, and physics. I suspect Math/French will be my best letters of rec.
Thank you very much!
