can someone tell me if im anywhere close to the ball park with this

[band_geek_litch]

I'm exempt from my history final, i have an 86.4 and hern said he would give me the 86.5, so for sanity's sake, lets say i have an 86.5 in history for the year.

I'm exempt, but the final seems easy and i wanna take it to maybe bring up my grade, but i dont think it can........

because

86.5 x .9 = 77.85

and if i get a 100 on the final, that's 10 points added to the 78 i have above

so the highest i can get for the year is an 88, so there is no point taking the final i am exempt from because it cannot raise my grade to an A-???

i think that's right
