TIPS ON SUBMITTING HW ASSIGNMENTS WITH WEBASSIGN The PHY131 WebAssign problems are designed to be a learning experience and as a practice session for your quizzes and tests. If you choose, they may be done in study groups, but remember that it is your effort in doing the HWs which makes the HWs valuable. Please, never use your browser's BACK button in the middle of an WebAssign session. The system is designed to only move in the forward direction. The way things are set up at this time, you will have 10 opportunities to answer each numerical part of each problem. For Multiple Choice parts, you only get TWO tries. To have your answer graded for a single part of a problem, fill in only that part and select the button "Submit Answer" which appears at the bottom of that problem. If a part has been left blank, no submission is charged for that part. Each incorrect answer will cost you a penalty of 3% of the available points for that part. For the first few assignments, the penalty will only begin on the second try. Always use three significant figures in your numerical answers (unless the program gives other instructions for a particular problem). Numerical answers must be correct to within 2% (with rare exceptions which are noted within the problems). Typing in more than three significant figures is a waste of your time. For the rare problem in which answers must be correct to a fraction of a percent, enter four significant figures; it is always a waste of your time to enter more than four sig figs. To enter a number in scientific notation, use the format *.**E**; for example 5.97 X 10^24 would be entered as 5.97E24. NOTE: There are some questions for which you have to "select all true statements." These are called "Multiple- Select" questions; on these questions, you get the usual number of submissions. Approximately 5 minutes after the due date for each assignment has passed, you will find a practice version of the assignment available. You may do this practice version as often as you like, but no credit will be given. The practice versions are found by going to "Past Assignments", then opening each assignment. At the bottom of each randomized question, you will find a button that allows you to practice the question as often as you like. If the button doesn't appear immediately, just click on the answer box for that question. TIPS ON SUBMITTING Test Questions WITH WEBASSIGN Please, never use your browser's BACK button in the middle of an WebAssign session. The system is designed to only move in the forward direction. The way things are set up at this time, you will have three opportunities to answer each question on a PRACTICE TEST, but only ONE chance to answer each question on one of the actual tests for a grade. The PRACTICE tests have no time limit, but the actual tests have a one hour time limit to answer the 12 questions. The PRACTICE tests may be taken anywhere, but the actual tests must be taken on the computers in the physics testing center in PSH-563. For the PRACTICE test, you may submit one question at a time, but for the actual test you must submit all 12 questions at once. When taking the actual test, do NOT hit the SUBMIT button unless you have filled in the answers to all 12 questions.
