Grade level is a variable, but since it is held constant among all study participants I agree that this should have been marked as only a known constant (5a) instead of a variable (5b). And regarding the TYPE of variable (quantitative versus categorical), I indicated that it "could be both" because yes, it is a category of student, but it is also a numerical value that has an intrinsic degree with actual amounts (age, abilities etc.) implicit in the number. Grades can be viewed in a manner similar to age, a variable that could be categorical or quantitative, depending on its use.
