Assume that the final grade in your biology course is comprised of several factors each of which is weighted as follows:
Laboratory: 25%
Final exam: 30%
Class exams: 20% each
Class participation: 5%

If you score 92 in the lab, 85 on the final exam, 75 and 82 on the two class exams and your class participation is 90, what is you weighted average in this course?

if you scored 92 out of 100, how much did you score out of 25?

The answer is 23 out of 25.
do the rest similarly and add them all up

Lab: (0.25)(92)=23
Final Exam: (0.30)(85)=25.5
Class Exam: (0.20)(75)=15
Class Exam: (0.20)(82)=16.4
Participation: (0.05)(90)=4.5

23 + 25.5 + 15 + 16.4 + 4.5 = 84.4
