My school uses this grading system: homework counts as 15% of your overall grade, quizzes count as 40%, and tests count as 45%. Anyways, I took a quiz on integers and I'm pretty sure I f*cked it up. there were about 4-5 questions out of the 25 questions that had integer equations and i did them the wrong way. there was an equation that said: 16-(-10). I though the answer was 6 because the way I see it, the -10 is moving down the number line 10 spaces, so i got 6. well, after i turned it in, i realized all my mistakes. our teacher doesn't let us take our quiz out of the basket, so i knew i was screwed, mainly because right now, i have an 88 in it. this may not seem bad, but i have really high standards for myself, so this is identical to failing. also, this is the last grading period we're going to get and i might not get a chance to redeem myself. what should i do to get my grade above a 93?
