computing average in nested loops

[cap510]

I can't seem get class weighted average to compute correctly. I ran program with placement under the two different loops, but each time it gave me an incorrect number.

students = ['Tony', 'Steve']
category = [ 'Assignment', 'Quizzes', 'Projects', 'Essays', 'Exams']
weighted = [.1, .1, .3, .25, .25]
cwave = []
total2 = 0
total3 = 0
for i in students:
    print(i)
    total = 0

    for num in weighted:
        score = float(input('Enter scores: ')) * num
        total += score
        total /= sum(weighted)
        total2 += total
        total2 /= len(students)
        if total >= 89:
            letter = ('A')
        elif total >= 79:
            letter =('B')
        elif total >= 69:
            letter =('C')
        elif total >= 59:
            letter =('D')
        else:
            letter =('F')
    print('Wieghted average = ' + str(total))
    print('Wieghted Letter Grade: ' + (letter))
print('Class Weighted Average: ' + str(total2))

This is what returns - It should compute to 84.225 -no error message:
