I need to get my shit together.

I am going to give the March SAT. Yesterday i took my first real practice test, I mean i took one before that in November but at that time i was tired and skipped questions. I took the practice test 4 and in November i took the practice test 1. In November i got a 1200 and now i got a 1220. My score in math increased but in English it decreased. This is my last chance and i need to get a 1400+. I cant take the test again and this would be my last chance. If i cant get a 1400+ i would have to change the programme i want to study so i need to lock in. For English anything above 650 is good and for math like i really want 750+. What should i do? Any tips would be appreciated.
