Question about calculating my grade?

Question

Grading Procedures:
There will be FIVE in-term exams (100pts each) and a final (150pts) in this class. The exams will be entirely in the multiple choice/scantron format. The final will be comprehensive. Class attendance is not mandatory; however, daily quizzes will be given for five points each. There will be no make-up exams without PRIOR approval and no late assignments will be accepted. A semester maximum of 40 points extra credit will be allowed. ABSOLUTELY, NO EXCEPTIONS TO THE RULES! YES THIS DOES MEAN YOU.

Exams are each worth 13% of your grade for a total of 65%
The Final Exam is worth 20%
Participation in class is worth 1%
In class quizzes are the remaining 14 %

Course Evaluation:
Evaluation of the student will be based on the departments' grading scale as follows:
A=90-100
B=80-89.99
C=70-79.99
D=60-69.99
F=0-59.99

How would I go about calculating my grade for my class? I was okay until it went into the stuff about precentages... thanks

Lets say I made an 87 on one exam, a 0 on another, and made a 70 for the remaining three exams. On the final I made a 80. I made 40 points for extra credit...
Out of 30 daily quizzes I missed 10, but made 5 points on the other 20.
How do I calculate my grade?

Answer 1

I computed a grade of 69.776% a D. Congratulations you snatched defeat from the jaws of victory. That 0 on the test really killed the grade and blowing off 10 classes didn't help.

Total points on test out of possible 500 = 297 which is 59.4%
I added your 40 point extra credit to your test scores
(297+40) = 337
337/500 = 67.4%

Class participation I figured that if you missed 10 out of 30 classes the best you could get would be 66.6% attendance. You can't participate if your not there.
You also got a 66.6% total on your quizes (20x5 =100)
100 points out of a possible 150

Now we weigh the above scores using the percentages which you said you had trouble with.

Exams 67.4 x .65 = 43.81
Final 80 x .20 = 16
quizes 66.6 X .14 = 9.3
participation 66.6 x .01 = .666

Add these up and you get 69.776%

HAD YOU GONE TO JUST ONE MORE CLASS.
You would have taken an additional 5pt quiz and been in class 70% instead of 66.6% your final grade would have been 70.3% a C !!!!!

Answer 2

How did you do in each section?
Lets say i got 90 on my first in term exam and then later 89, 99, 95, 98...
Then on the final i got 142.
i got 100 on each daily quizz, and attended them all.
and i did the 40 points extra credit.
so the extra credit makes up for the exam questions i missed, and it brings the final score up to 150 and i am left with three extra credit points. So up to now i have 100 percent in every thing...plus the 3 extra points.
now since i did all the quizes that is 100 too. So my grade is an A.

Answer 3

Participation in class is the unknown because you are at the whim of the teacher or worse if you never participated in class. So you have at lease a 1% error or margin in whatever you figure.
