Early application November test?

So I plan on retaking the sat and I’m yet to take the Subject tests. I plan on taking atleast 2 subject tests. The question I have is for early decision and action, am I better off taking the SAT in October or my subject tests? I need a good boost for my math section for sure. Also, if I take the subject tests in November, which most colleges accept, will I be able to see my scores before I send them in?
