If you currently have a 94, getting a 60 can significantly lower your grade depending on how much the assignment is worth. A low score on a heavily weighted test can drop your grade by an entire letter.
Current grade: 94
Assignment weight: 20%
Score: 60
→ New grade: ~87.2
If the weight is higher (like 30%), your grade could drop even more.
