I Have A Question For Teachers...About College?

Allr ight so 'm a Junior, well going to be a Senior! So this was my most important year as colleges ccare about my grades the most this year. I kinda suck at US Histroy (I SUCK at Social Studies) so my averages each semester were like upper 70's. On the regents however, I got a 91. Will colleges look at this and say she had a bad teacher or a hard teacher? Cuz Im kinda worried cuz i averaged out 70's my last two semesters.
