Each section of the class is worth the following percentages

Each section of the class is worth the following percentages.

Attendance ................... 03 %

3 Mid-term Tests.......... 39 % (13 % each)

In-class Quizzes ........... 03 %

Lab............................... 10 %

Homework ................... 15 %

Final Test................... 30 %

If a student receives the following grades at the end of the semester:
    

Attendance = 95%
    Test 1 = 75%
    Test 2 = 85%
    Test 2 = 75%
    Final Test = 62%
    Quiz = 71%
    Homework = 82%
    Lab = 88%

What is the student\'s final course grade (as a percentage)?

Solution

All we gotta do is this :

Weightage of attendance is :
3% of 95% as in 0.03*0.95 etc etc

So, we get :

0.03*0.95 + 0.13*0.75 + 0.13*0.85 + 0.13*0.75 + 0.1*0.88 + 0.15*0.82 + 0.3*0.62

0.731
