Answer 1

do you mean restrictions?

Answer 3

Grades in classroom are usually 0 to 100

Answer 4

Teachers might want to give negative grades but they can't. Students may need to make a 150 to pass but they can only make a 100.

Answer 5

ok there is this fantasy of extra credit and then some grades go up 105 or so but the programs are restricted and will override the grades to 100.
