Now, @DrBob222, you must be searching for these questions or something, because every question that says "quick check" you say that exact same thing...
Lets get this straight,
there is a certain school, where the assignments are sorted by what they are about or review:
Quick Check: a short, to the point assessment that gives questions that go over the topics in the lesson. It is provided to "Quickly Check" your understanding of the topics in the lesson
Quiz:longer than a Quick Check, but shorter than a test. same thing, except for a slightly higher grade.
Practice: not for a grade, but it helps to see what you do and don't understand in the lessons
@DrBob222, i suggest you CHECK YOURSELF BEFORE YOU WRECK YOURSELF, and don't ASSUME things.
