How do you determine final grade?

My grades for my government class are as follows-100,100,80,77,50,42 and 10. Im not sure how they determine the final grade. These are not my actual grades because i went on the grading program in school and changed my grade to make it higher. So i need to know what the actual grade would be to avoid suspision.How do you determine final grade?
I don't think it's too wise to tell people that you went on the grading program and changed your grades.



Not to mention that it's a reason to get expelled...



So I wouldn't worry too much about getting suspended for having poor grades.



But, if you must know, it depends on how your grades are averaged.



Do tests and quizzes carry more weight than homework assigments?? (For example, are tests 50% of your grade, and homework and class participation another 50%)



However, if everything is worth the same, just add everything up and divide it by the number of grades.How do you determine final grade?
Wow thats just stupid. If you were smart enough, you would only change your grades a little, not by alot so it wouldn't be obvious. If you have to change youre grades in school just to get better grades, thats pretty sad.
You take all your grades ADD them up then divide each term, When I did this w/the grades you gave it comes out to be a 60 Failing I hope these are not your grades, the 50,and the 42 and 10 brought those two A's and the 80 and even the 77 way down. So as you have stated that these are not your grades I sure hope not if so you will be suspended. Take Care
