I am a Junior in high school and I have a 83% C+ in chemistry this semester and a 95% A last semester. We are about to take a test, the last one of the year, and i want to exempt from my final exam. To do that I have to have an A for the entire semester, a 95% what is the lowest grade I can get on this test to get an A for the semester. How do I figure this out? plz report back ASAP!!!
