This is an example explaining how to use the calculator.

Do not leave any spaces in between each score or add percentages, this confuses the calculator.

 

Jack has a final exam coming up in a few days for his History class… He is unsure of the grade he needs on the final exam to pass the class with a B.

And to ease his anxiety, he found our grade calculator to help him figure out what he needs to make on his final exam to pass the class.

 The class is outlined on the following structure:

tests, worth 15% each (45% towards final grade)

10 quizzes, worth 3% each (30% towards final grade)
1 final exam, worth 25%

Jack made 72, 85, and 76 on his three tests.
Jack’s quiz grades are 100, 90, 100, 100, 100, 80, 0, 90, 70, and 90.

 

Step 1: Jack enters his scores 

Jack enters the grades he has received so far into the cells at left. In each row of cells, he enters a grade he received in the left cell and the amount that grade counts toward the final average in the right cell. For example, the rows

72 15
85 15
76 15

indicate that Jack’s test grades are worth 15% each.

Notice Jack typed 15, not 15%, in the right column. Typing percent signs will confuse the program.

Also note that Jack did not convert the numbers to decimals; i.e. he did not type .15 in the cells to indicate a weight of 15%. Simply type 15 to indicate 15%.

The quizzes are slightly more difficult, but we can handle them. There are 10 quizzes, worth a total of 30% of the total grade. This means that each individual quiz is worth 30 divided by 10, or 3%, of the final grade. Therefore, Jack enters a 3 next to each quiz grade.

100 3
90   3
100 3
100 3
100 3
80   3
0     3
90   3
70   3
90   3

Step 2: Jack enters his professors grading scale into the Letter Grade Section

(Jack’s University uses a plus-minus grading system.)

In order to receive an A in the class, his final average must be at least 93, so he types

A 93

in the first row of cells. He needs a final average of at least 90 to get an A-, so he types

A 90

in the next row. He repeats the process for B+, B, and so on.

 

In order to receive this grade Your final average must be at least

Do not skip any rows or add any percentage (%)

Jack continues to change what his ideal final exam grade would be using trial-and-error.

After changing his ideal exam score to be 90, he was able to boost his final grade to an 85%
