Subject Test Submission to Top Schools

Should I report both SAT II scores or just my Math score to Top-20 colleges?

My stats are 36 ACT, Top 10% of class, 800 SAT II Math 2, 740 SAT II Chem. I’ve read that I should only send subject tests with scores of 750+, so I’d really like some thoughts on this.

I want to major in a STEM major- possibly neuroscience.
