If I have an 82 in a class right now and a test is 50% of my grade but I get a C what would my total grade in the class be
That depends on what is considered a "C"; 70%? Average the two, 82 and whatever constitutes a "C" to find out your final percentage, since they will count the same.
To calculate your total grade in the class, you will need to take into account the weightage of the test and your current grade. Here's how you can do it:
1. Find the weightage of the test: Since the test is worth 50% of your grade, convert it into a decimal. 50% is equivalent to 0.5 (50/100 = 0.5).
2. Calculate your contribution from the test: Multiply your test grade (C) by the weightage of the test. Since a C corresponds to a grade of around 70-79%, let's assume you received a 75%. So, multiply 0.5 (weightage) by 75% (0.75 as a decimal): 0.5 * 0.75 = 0.375.
3. Calculate your current grade contribution: Subtract the calculated contribution from the test (0.375) from your current grade (82%). To do this, multiply your current grade (82%) by its weightage (1 - 0.5 = 0.5): 0.5 * 82% = 0.41.
4. Add the two contributions: Add your calculated contributions from step 2 and step 3 to find your total grade contribution. 0.375 + 0.41 = 0.785.
5. Convert the total grade contribution to a percentage: Multiply the total grade contribution by 100 to get your total grade in percentage form. 0.785 * 100 = 78.5%.
Therefore, if you receive a C on the test, your total grade in the class would be approximately 78.5%.
