If there are 20 questions then each question is worth 5 points because 100 total points divided by 20 equals 5.If you missed 8 questions then 8 times 5 points equals 40 points wrong, so you have to subtract that from 100 to get a grade of 60. Study harder next time.

40/8=5
most stop in grade 6, or if you go to a K-8 school, usually grade 8
It depends on the test. Some tests penalise wrong answers, others don't.
8/13 right = 62 %

Exactly 8 times
It goes up to grade 8 I believe
