Post Quiz Chemistry A
This is the post quiz for chemistry A. This is the same quiz you did for the pre-test at the beginning of the course. The points will now count. You will need to take BOTH the post quiz and the semester exam. This post quiz is NOT LINKED to the K12 LMS. I have to manually move your score to the grade book. Please patient and wait for me to do this. Thanks. You do NOT need to k-mail me your certificate. I can pull your score from this web site. Thank you! Mrs. L.
