1. Does anyone say “a course quiz” or “a class quiz” to refer to a quiz in school? 2. “A quiz of/for this course.” Which preposition is correct? Thanks.

I'd almost never say I have a "class quiz" or "course quiz." (Unless you're using "course" or "class" as a space holder for a specific class.) I'd say a "math quiz" or "a quiz in math class."

Try "in". "I have a quiz in English" or just "I have a quiz in class".

You just use whatever class you’re talking about as an adjective to describe the quiz. If it was in science class, you’d say “ I have a science quiz”

"A quiz of this course" sounds like a quiz about the course itself -- like a quiz about the syllabus content. This sounds strange and incorrect. "A quiz for this course" is a quiz you are taking on course material. This sounds correct. We can say "It's required to take a quiz for the course" if we are talking about purpose (what we usually use "for" for). We can also say "It's a quiz on thermodynamics" to talk about the general subject. "In" is also acceptable, but it can imply a broader field, and is less common (and therefore sounds a bit odd). We can also not use any prepositions: "math quiz", "geography quiz", etc. We take the quiz "in class" or "during class". > A: I'm stressed about a quiz coming up. > B: Oh? What's the quiz on? > A: Newton's laws. > B: Oh? What's the quiz for? >A: Physics 101. >B: Oh? What's the quiz in? > A: Physics. >B: Oh? What kind of quiz is it? >A: A physics quiz.

What exactly are you trying to express?

>1. Does anyone say “a course quiz” or “a class quiz” to refer to a quiz in school? No. As others have said, we'd use the name of the course. "A math quiz" or "a history quiz" >2. “A quiz of/for this course.” Which preposition is correct? "A quiz for this course" is grammatically correct, but sounds a little awkward. What is the full sentence you're trying to say?
