Calculation of averages
Calculation of Averages Every term, students are tested a number of times on every subject and the different test results are used to calculate averages for the different subjects. These averages reflect student performance in the different subjects, higher averages indicating better performance. Most schools use simple arithmetic averaging methods, such that a student who gets in a certain subject a 40% on one test, a 60% on the second, and an 80% on the third, gets an average of (40%+60%+80%)/3 = 180%/3 = 60%. Another student whose average for the same subject over the same interval is 70%, for example, is considered to have done better than the previously mentioned student.
