I have an 80 in my sports medicine class, but we took a test. The test is 60% of the grade. Will it affect my grade?

Grade averages are usually calculated as weighted averages. This means that grades on assignments that are worth a higher percentage have more of an effect on the the final grade average. Whether your test grade will impact your current grade average of 80 depends on what grade you made on the test.

To calculate a weighted average grade, each grade is multiplied by the percentage that the grade is worth. The resulting answers are then added together to give the final grade. 

In the case of your sports medicine class, your test is worth 60%. So, your other grades will be worth 40%. You indicated that you have an 80 for your other grades. 

Now, let's look at some different scenarios.

• If you made a 90 on your test, you would calculate your final grade as follows: (80)(.40) + (90)(.60) = 86

• If you made a 70 on your test, you would calculate your final grade as follows: (80)(.40) + (70)(.60) = 74

• If you made a 50 on your test, you would calculate your final grade as follows: (80)(.40) + (50)(.60) = 62
