If you got 20 problems wrong on a 75 question test your grade would be 73% or a C. You can find that by subtracting the amount of questions you got wrong from the amount you got right, 55 in this case. Divide the amount of correct questions by the amount of questions on the test to get .733333. That is the grade.

How do you find your final grade?

In most grading systems, your final grade is the average of your semester/marking period grades. Your mid-term and final exams might be separate and worth a percentage of your final grade. For example, in a high school divided into four marking periods, each marking period might be worth 20% of your final grade, and the mid-term/final exam might be worth 10% each of your final grade. Bottom line is that it depends on your individual school or college course. Each one may have a slightly different way of calculating your final grade, and you should contact them for specifics.

What is the equation you use to find what grade you need to get on a Final to maintainbring up your grade?

It depends on the weight given to the Final Exam. However, Here is an example where there are three components to the final grade, Attendance, Quizes and the Final Exam: {D - W(A) - X(Q)}/Y = Grade Needed on Final Where D = your desired final Grade. W= the weight given to Attendance (like 20%) and A=your current Attendance grade. X=the weight given to Quiz grades (like 30%) and Q=your current Quiz grade. Y=the weight given to the Final Exam (like 50%) W + X + Y must = 1 (100%) So, if you want to end up with a final grade of 90, and your Quiz scores average 80 but you have a 100 in Attendance, the formula is: {90 - .2(100) - .3(80)}/.5 = (90-20-24)/.5 = 46/.5 = 92 grade neede on Final If there are more than 3 components, the weight and current grade would go into the formula just like W(A) and X(Q), as a subtraction from D. Just make sure that all your weights always add to 1.
