Read the following carefully and then click the link at the bottom to proceed to the quiz.
The exam mode of WeBWorK, called Gateway/Quiz, has several differences from the homework mode. Instead of submitting each answer as you enter it, you submit all of the answers entered hitherto, every time you push the Grade button. You may push the Grade button no more than four times during the test. You may still look ahead, and work the problems in a different order than they are presented. When you first open the test, a timer appears that will count down your allotted 75 minutes. WeBWorK will start urging you to finish when there are 90 seconds to go. It will stop accepting answers either after you have pushed the Grade button four times, or after time has run out.
Important note #1: during the quiz, you may consult ONLY the ASTR 106 website. You may not conduct internet searches, nor any other website, nor each other. You must silence your cell phone and put it away; you may not use it during the quiz for any reason.
Important note #2: do NOT open two WeBWorK windows or tabs at the same time while you're taking the test. It's safe to leave or log out of a WeBWorK session (pushing the Grade button before leaving, of course), and then to log back in, but it causes difficulties for the database for one certain kind of quiz problem, if one is logged in twice.
Important note #3: if you start your test or press the Grade button when lots of other are too, it may take more than the customary 5-10 seconds to reload. This doesn't mean that there's something wrong. Be patient.
Important note #4: You get four presses of the Grade button in order to minimize the chances of losing answers, either to network outages or to inadvertent mistakes in entry. Space them evenly throughout the test. Do not save them all til the end in an attempt to guess down any problems -- there are too many problems on the test for that to work.
In quiz mode, there is no Feedback button. However, we will be in the room with you to answer any questions that arise. Note that, since this is a real test, we will only answer questions to clarify, not to help lead you to the answer, as we would in recitation or office hours.
As usual, enter your numerical answers with at least three-significant-figure precision. To use scientific notation, write your answer in the form xxE+yy. It is important that you use a capital E; answers with a lower case e will be evaluated differently.
Every time you push the Grade button, you will get an update of which problems you have answered. WeBWorK will remember the best answer you submitted for each problem in your final total. If you submit an incorrect answer for a problem to which you have previously submitted a correct answer, that problem's points won't appear in that particular submission, but will appear in your final total.
After closing time, anybody may download a copy of their quiz, checking the boxes for "Correct Answers", and get a PDF with their own solutions and the correct answers.
