Peaked and declining…

On full PTs, I scored a 178 and 179 in my PTs and then was scoring slightly lower at 173-176, but now I’ve scored 172 twice in a row. I can see I’m capable of that near perfect score, but now I am worried about the recent decline especially as I get close to the April test date.

For the entire time, I’ve been taking a full PT and blind reviewing on weekends and taking 1-2 sections on weekdays to take 2-3 tests a week.

Has anyone else experienced similar score declines and how did you combat them?
