Can someone help me figure out how much my final exam is weighted? in the grade book there are:
6 assignments for 10 points each
52 assignments for 20 points each
5 assignments for 30 points each
5 assignments for 40 points each
and 1 assignment for 60 points (aka the final exam)

my grade is an average of all of these different assignments combined. How much is my exam weighted- can you even calculate this? (i just want to know so i can see what score i need to get to pass with an a)
