How to calculate your grade:
Example 1:For course grades weighted as follows
(see your course syllabus for this info):
Exam 1  20 % 
Exam 2  25 % 
Exam 3  25 % 
Exam 4  30 % 
For student Calcite Karst, his grades are as follows:
Exam 1  85% 
Exam 2  85% 
Exam 3  75% 
Exam 4  88% 
Mr. Karst's grade is calculated as follows:
calculations  
Exam 1  20% (200 pts)  170 
85 x 2 = 170  
Exam 2  25% (250 pts)  85 x 2.5 = 212.5  
Exam 3  25% (250 pts)  75 x 2.5 = 187.5  
Exam 4  30% (300 pts)  88 x 3 = 264  
Total  100% (1000 pts)  834 
170+212.5+187.5+264=834 
Mr. Karst earned a total of 834 of 1000 points which is 83.4% = B.
Example 2: What score would Ms. Marianas have need on the Final (Exam 4) to get an A in the course?
To earn an A, Ms. Marianas must accumulate a minimum of 900 points (90% of 1000).
weight  calculations  
Exam 1  20% (200 pts)  93 x 2 = 186  
Exam 2  25% (250 pts)  207.5 
83 x 2.5 = 207.5  
Exam 3  25% (250 pts)  237.5 
88 x 2.5 = 220  
Exam 4  30% (300 pts)  
Total  100% (1000 pts)  186+207.5+220=613.5 
Before taking Exam 4, Ms. Marianas has 186+207.5+220=613.5 points
(900613.5)= 286.5 points needed to get to 900 for the term.
286.5/300 = 95.5% for Exam 4.
To earn an A in the course, Ms. Marianas must score above a
95.5% on Exam
