1. A student who is intently and primarily focused on getting good grades. I know some of the kids in my class are just grade-grubbers—anxious to get an A above all else.
2. A student who tries to persuade the teacher to change their grade, as through flattery or questioning. He only complimented your outfit because he's a grade-grubber who wants you to turn his B into an A. All the grade-grubbers are saying that I misled them with how I worded one of the questions on the test, ugh.
1. n. an earnest, hardworking student. (In the way a pig roots or grubs around for food.) If there are too many grade-grubbers in a class, it will really throw off the grading scale.
2. n. a student who flatters the teacher in hopes of a higher grade. A few grade-grubbers help assure old professors that the world is not really changing at all.
