I have a week for the SAT (giving it October 3rd). My last score was a 2090. What are the chances of bringing it up to a 2200? Also, my plan is to give a practice test tomorrow morning, and then revise my mistakes up to test day. On the side, I’ll continue to read good books and improve my vocabulary. Does this look like a proper plan? Any suggestions?

If there was one thing I wished more people understood (both in the context of this site and in my actual tutoring business) it’s that there’s really no way to know how much someone can improve. It’s a fool’s errand to try to guess. So cannot, in good faith, answer your first question.

As for your plan, that sounds like a good and reasonable approach to the last week before your test. Good luck!
