Final Grade Calculation
# record point scores for tests
test1 (out of 80)
test2 (out of 80)
final (out of 120)
# normalize second test score using averages
test2n = test2 * test1avg/test2avg;
# pick higher test
lower = test1 OR test2n
higher = test1 OR test2n
# calculate final percent grade
percent = 0.45*higher*(80/100) + 0.15*lower*(80/100) + 0.40*final*(120/100)
