Weighted grades are number or letter grades that are assigned a numerical advantage when calculating a grade point average, or GPA.
Compute the weighted grades in the blank columns next to each raw grade. So, in the example, in cell C2 enter =B2 0.035. Copy this to cells E2, G2, I2, K2, M2, O2 and Q2. In cell S2, enter =R2 0.30 and in cell U2 enter =T2*.4. Copy these cells down the columns for all your rows of data. Compute the raw grade.This is the sum of all the weighted grades.In the example, enter =C2+E2+G2+I2+K2+M2+O2+Q2+S2+U2. Copy this cell down the column. Convert to a letter grade. First, decide on which numbers match which letters.opy these cells down the columns for all your rows of data. Compute the raw grade. This is the sum of all the weighted grades.
