If my mid-term is worth 15%, and my grade is 100% right now. If I get 0 on the exam, my grade would be 85% right?
no, you'd get a 15%
If you got a 0 on the midterm and 100 on the exam, you'd get 85%.
To calculate your grade, you need to take into account the weightage of each assignment. In your case, if your mid-term is worth 15% of your final grade and you currently have a grade of 100%, you can calculate your potential grade by following these steps:
1. Determine the remaining weightage: Since the mid-term is worth 15%, the remaining weightage that needs to be distributed among other assignments is 100% - 15% = 85%.
2. Calculate the weighted grade of the mid-term: Multiply your current grade (100%) by the weightage of the mid-term (15%) to get the contribution of the mid-term towards your final grade. In this case, it would be 100% * 15% = 15%.
3. Calculate the remaining weighted grade: The remaining weightage of 85% will be distributed among other assignments. Since you expect to score a 0 on the exam, the weighted grade for the remaining assignments will be zero.
4. Add up the weighted grades: Sum up the weighted grade of the mid-term (15%) and the remaining weighted grade (0%). 15% + 0% = 15%.
Therefore, if you get a 0 on the mid-term, your overall grade will be 15%.
