If I had an 81% in class and my previous test I got a 92 and my final exam I just got 202 points out of 200. My exam was worth 30% of my grade.

Question

After having an 81% and getting a 92% on a test, and then getting a 202 out of 200 on the exam (worth 30% of my grade) whats my final grade now?

Answer 1

Congratulations on 202 out of 200 on Final Exam. Suppose that the "92" last test has weight "L" (%) and the prior "81" has weight (70-L) % and the Final Exam's "101" has weight 30%.

 

Then your score for the entire semester is [81(70-L) + 92L + 101(30)]/100,

 

If L = 10, then your grade is 88.1
