if my grade is an 81% and i get a 51% on a test weighted 10% what's my grade now
To calculate your new grade after receiving a 51% on a test weighted at 10%, you would first calculate the impact of the test on your overall grade.
Your current grade is an 81%, which makes up 90% of your overall grade since the test is weighted at 10%.
To calculate the impact of the test on your grade, you would multiply the test grade (51%) by the weight of the test (10%).
0.51 (test grade) * 0.10 (weight of test) = 0.051
Next, you would subtract this value from your current grade to determine your new grade:
81% (current grade) - 5.1% (impact of the test) = 75.9%
Therefore, your new grade is approximately 75.9%.
