I’m just asking for help to interpret the two statements: “She had her 1st test this week in psych and got a 75.” and “Unfortunately when the professor sent out the grades, he also said that a 4 kids got 64/65.” The two different uses of descriptive language leave me in doubt as to whether I understand the situation. “My school” was many decades ago, and (I think) we tended to have multiples of 100 for tests. </p>

No, that actually does matter; it makes a quite strong statement. If four students were able to score 64 of 65 total, that means perfection in this test is quite possible, and 75 really could be a mediocre grade. That’s hugely different than a situation where, for example, nobody in the class of 200 scored more than 20% (I’ve been in a few such classes).</p>
