If you scored a 770 on the math SAT2 test what will you score on the math part of the SAT?

I scored 770 on SAT Math and 770 on SAT math 2 and 750 on math 1. math 2 is very easy to get a high score because of the very generous curve (i missed around 8 and got 770, however I know I could had gotten 800 since I made stupid mistakes). However, on the math part of the sat I missed only 2 and got 770.
