For grading homework get only money not points.
You get more points for grading than actually doing homework, which some abuse.
I think it would be fair to get rich from gradings but not to get points. Or at least get less points than for actually doing the work.
Its disappointing to work hard on a homework for an hour, then spend 10min grading and get more points for grading.
The level for grading should be higher as level 3 which you have after 3 days. By that time you got 20 comments to your homework and some of them are graded by copy and paste E's.
