Pre- and Post- Laboratories

Pre-labs and Post-labs are assigned to insure that you come to the laboratory prepared to conduct each week's experiment, and to test your retention of the material learned. A pre-lab is always due the day of the experiment, but a post-lab may be conducted several weeks after the conclusion of the experiment.

All questions are turned in using WebAssign. You will need an access code purchased through the Cadet Store to use the system. This code should have been included with your text-book for the accompanying physics course. If you do not have it at the beginning of class, the system gives you a two-week grace period to acquire it. To log in, go to www.webassign.net, and fill out the Log In form on the right side of the page. Your user-id is your first initial and last name, your institution is Citadel, and your password is the last four digits of your Citadel ID number. For example, if your name is John Smith and your ID number is CIT-07-1234, then your user-id is jsmith and your password is 1234.

No submissions are accepted after 7:00:00 AM on the due date, by WebAssign's clock. Extensions for known conflicts require previous approval, and are given only in rare cases. Emergency extensions are possible only if you have not viewed the set after it was due, when the answers are available.

In the event of a wrong answer, don't be overconfident: grading errors are very rare, and the problem is almost always with the answer. A common error is to enter too few digits, or to keep too few in intermediate calculations. WebAssign normally expects an answer to be correct within 1%, which requires at least three digits to be used throughout calculations. If you are in doubt about an answer, you can send me an e-mail if you start early enough to leave time for an answer. (The last night the set is open is probably too late.)
