Does this grade sound correct?
In my math class, we took our first quiz today and I know I got no higher than a 60%. We have no other grades entered besides homework and this one quiz. I have turned in every HW assignment since the first day. So, given that, wouldn't I have had 100% before this quiz?
Our teacher weighs our quizzes and HW as 15% each. So, given that info, wouldn't that mean I would have to get a 0% on that quiz for my grade to drop 15% from a 100% to an 85%, right? Soo... if I failed that quiz my grade would only drop, at the most, like 3-5%? Help would be much appreciated. I am worried.

If homework and the quiz are both worth 15% and you have no other grades, then right now they are both worth 1/2 of your final grade, or 50%.
That means, if you had 100%, and then got 70% percent on your quiz, you average would be 85%.
You got 100 out of a possible 100 on your homework, divided in half that is 50 (so it's now 50 out of 50).
If your homework is worth 50 of 100 possible percentage points of your final grade, you got all 50 of those points.
On your quiz you got 70 out of 100. 70 divided in half is 35 (That is now 35 out of 50). If your quiz is worth 50 of 100 possible percentage points of your final grade, you got only 35 of those points.
50 plus 35 equals 85.
If you got 100% on your homework, and your average is now 85%, then you received a 70% on your quiz.
If you had gotten zero on your quiz, your grade would be %50, because all you would have, is the 50 points you earned from your homework. It doesn't matter that they are both only worth 15% in the end, because there is nothing else right now. They are worth more. They are both worth 50%.
