Quizzes: Grading
                Basic Skill Deadlines

Quizzes: Reviewing Scores

Quizzes: The difference between a request (limited to 8 per day) and a submission.

Quizzes: Error Messages (and what to do about them)

Quizzes: FAQs (Frequently Asked Questions)

WARNING: DO NOT put these off until the last minute. If you miss submission  deadlines or encounter computer problems at the last minute, extensions WILL NOT be given.

If you are having problems with your computer that prevent you from taking the quizzes, try a different computer and/or go to a PSU computer lab. If you still cannot take them from a PSU lab, then report the problem to your instructor.

Note you have a daily limit on the number of times you can request a test, but no limit on the number of submissions. This limits the number of times you may request a test in any 24 hour time period to 8.

If you start requesting/submitting at 6:08 pm and use up your 8 requests in the next 3 hours, you will NOT be able to take that specific test until 6:08 pm the next day when the attempts begin to  expire—that is, the 24 h, in this particular example, runs from 6:08 pm until 6:07 pm the next day. It does not start at midnight. Midnight is the deadline only wrt to the bonus and final deadlines.
