Taking SAT again... some tips please

Hi,

I took the SAT last October and got a 2100 (740M, 670R, 690W (9 essay)) (studied a lot for this score). I am planning on taking it again this December (it will be my last and 3rd time). Does anyone have any tips to increase from a 2100 to a 2200+? Also, how to study for vocab? Thanks in advance :slight_smile:
