Don't ask me how I am in college and taking diff equations and I don't know how to do this.... I'm having a brain fart. Thanks!

## Replies to: How do you calculate your final grade (like: exams worth 70%, final worth 20%, etc.)?

1,185Registered User Member187Registered User Junior MemberWould you do (for example with the exams):

(exam average) X (percent of final grade) = points earned

and then add up all the points earned to get your final grade out of 100?

9,678Registered User Senior MemberB, B+ on two midterms, each worth 30% of the final grade

C on final, worth 40% of the final grade

0.3 * 3.0 + 0.3 * 3.3 + 0.4 * 2.0 = 2.69, which would probably round to a 2.7 = B-

If your grades are just on a percentage scale, you would do the same, except that your final result would only be a percentage and it would be up to the professor to decide where the cutoff for each grade is.

80%, 85% on midterms, each worth 30%

70% on final, worth 40%

0.3*80% + 0.3*85% + 0.4 * 70% = .... You do the math :)

187Registered User Junior Member726Registered User MemberLets say you have 2 exams worth 35% each (exams total worth at 70% like you said). The first exam you got a 70% and the second you got a 82%.

70% of 35 is 24.5 and 82% of 35 is 28.29

So right now you have attained 52.79 instead of the max 70% the exams are worth.

30+70 is 100% of your grade, 30 + 52.79 is 82.79. This means if you got a 100 on the final (the entire 30% it's worth), you would only be able to get an 82.79 in the class.

For example if you want to know what grade you want to keep a B (an 80), it would be a 27.21 (because 27.21 + 52.79 = 80) out of the 30% the final is worth or a "90.7%" on the final.

187Registered User Junior Member3,834Registered User Senior Memberi find that simpler than what specify did, but then again i'm a journalism major ;)

187Registered User Junior Member4,216Registered User Senior Member1,437Registered User Senior Memberit's all weighted average.

whether your professor converts straight from letter grade to grade points OR from percentages to letter grade or whatever mix, you still end up with the same result.

So for example say a class has the following grading policy:

30% midterm, 30% final, and 40% project

you end up getting an 80 on the midterm, a 90 on the final and a 85 on the project.

(80*.30) + (90*.30) + (85*.40) = 85 avg = B

OR

you end up getting an B- on the midterm, a A- on the final and a B on the project. convert the letter grades into grade points. B- = 2.7; A- = 3.7; B = 3.0.

(2.7*.30) + (3.7*.30) + (3.0*.40) = 3.12 which would fall under B since you have to round off to the closest letter grade. If the professor is nice enough he might give you the B+, but for statistical purposes that's how it's done.

every professor has their style of grading. some are more generous with their grading than you think. others also grade on a curve. so none of this may even apply to you.

numbers and n are subscript. n is the number of "categories". ie. if you have assignments, tests, pop quizzes, finals, and midterms. n=5

Just curious, how come your final is worth only 20%? What are the other "exams" like?

1Registered User New Member1,437Registered User Senior Memberi don't know if the 80% is the rest of your grade before the final, but assuming that's the case, then basically you're saying you've gotten 80% of the 100% that you can possibly get up to this point which basically means even if you fail the final you'll still pass with an 80%.

again you might want to state the exact scores you have and how much they are equal or weighted.

726Registered User Member.8*80+.2*(final_percent)=69.5

final_percent = 27.5

If you have an 80% in the class thus far and the final is worth 20%, then you only need to get a 27.5% on your final to get a 69.5% in the class.
