In practice, the phrase “studying for a test” was almost redundant, because that was when one really studied. The difference between diligent and slack students was that the former studied hard for tests and the latter didn’t. No one was pulling all-nighters two weeks into the semester.
Even though I was a diligent student, almost all the work I did in school was aimed at getting a good grade on something.
