Existing scores and # points the scores are worth:
1) 75% on a 10 point quiz
2) 80% on a 20 point test
3) 86% on a 30 point test
Assuming it's for the same class and all these points have equal worth:
The 30 point test or 20 point test are almost equal in terms of possible points earned back.
14% of 30 is 4.2
20% of 20 is 4
25% of 10 is 2.5
