Step 1: Enter your scores
First of all, list the grades you have received so far. Enter the grades you have
received into the left column; in the right column, list the percentage that each grade counts toward your final
average. For example, if you made a 95 on your first test and it counts 20% of the final grade, you would type
in the first row. Do not type percent signs in the right column; this will
confuse the program.
Of course, the numbers in the right column should not add to more than 100, since you cannot possibly
have received more than 100% of your total grade.
There is room for you to type 20 grades and their corresponding weights.
An example is available if you need help.
