Grade Calculator

The final grade will be calculated according to the following weighted percentages:

Exams and Practicals - 75%

Lab Assignments - 25%

### Calculating the Grade

Calculation of Grade using Weighted Percentages (as per the course syllabus):

Lab Score: The number of labs completed, divided by the total number of labs, multiplied times 0.25 (25%).

Practical/Exam Score: Total points earned on all lab practicals and exams, divided by the total possible points for all lab practicals and exams, multiplied by 0.75 (75%)

Add the Lab Score to the Practice/Exam Score then multiply by 100. This will be the grade for the course.
