Sending in SAT or ACT Scores?

Okay so for a lot of schools, I know that you can either send ALL of your SAT scores, or ALL of your ACT scores (or I believe both is an option?). Though I’m planning to take both the SAT I and the ACT again this fall, I still have a strong feeling I will do better on my ACT. I was wondering which seems like a better option to send:

SAT I:
R: 680, M: 700, W: 690 (Combined: 2070)

SAT II:
Bio M: 790
World History: 620
Chem: 780
Math I: 780
Math II: 760

ACT:
33

Using http://www.act.org/solutions/college-career-readiness/compare-act-sat/ your ACT score is the higher of the two. If you are planning on only submitting one, I suppose it makes more sense to send the higher.
However, that is quite the impressive list of SAT IIs, and many schools recommend those (or the ACT+ writing, did you take the writing portion?) so you should decide based on the specific schools’ requirements.

I did take the writing section on the ACT- I got an 8. A lot of the schools I’m applying to either recommend or require 2 SAT II scores. Would it be smarter to send both?

Send your ACT and the Bio, Chem, and Math II subject tests.

The vast majority of schools don’t require you to send all SAT and/or all ACT. Only some of the most competitive. Those schools clearly outline that on their web sites. Also, some schools don’t even consider SAT IIs. Check the Common Data Set, section C, to see if they do.
