If you have a 86% grade in science and you get a 63% grade on a test. What Is your new grade going to be?
To calculate your new grade, you need to know the weightage of the test. Assuming the test is worth 20% of your total grade, you can calculate the new grade as follows:
(86% * 80%) + (63% * 20%) = 68.8% + 12.6% = 81.4%
Therefore, your new grade would be approximately 81.4%.
