Check-In Quiz 3
Exams are spaced roughly 1 month apart in this course. Check-In Quizzes were written to cover the material between each exam as a sort of road marker between major assessments. While these quizzes are not graded or collected, they can be used as mini-exams to test your self half way through a unit. Think of it as an informal way to check your understanding halc way through to the next exam.
