V2 control quiz seems early

the control flow quiz, if i recall correctly, assessed knowledge of topics that were covered later, such as iterators.

This is still an issue. For all the other quizzes, the information is presented and THEN the quiz is given. But the control quiz is given before the relevant information is presented (it’s mostly been covered in application prep, but still). I guess you could rename it a “Pre-test” if you wanted to leave it in its current position?
