How to calculate weighted grades?

<p>I mean within a class. Like say the teacher has the individual section grades, and the percent that section is worth of your final grade, how to you determine what your grade is?</p>

<p>Take the percentage and multiply it by the grade it correlates to. For example if a teacher has something like this for your overall average:
75% tests
15% quizzes
10% daily</p>

<p>and you have a 90 test average, a 100 quiz average, and an 80 daily average, you would do
[.75<em>90]+[.15</em>100]+[.10*80]
which would give you a 91.</p>
