Instructions for Exam #1

Read the following carefully and then click the link at the bottom to proceed to the exam.

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: 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 exam problem, if one is logged in twice.

Important note #2: After starting a version of the test, you can return to the WeBWorK starting page, and download a pdf copy for printing: just proceed to use the Download Hardcopy link on that page, and print the resulting pdf

Important note #3: if you start your test or press the Grade button during peak hours, it may take more than the customary 10-15 seconds to reload. This doesn't mean that there's something wrong. Be patient.

Important note #4: The reason you have four presses of the Grade button is to minimize the chances of losing data to network outages or 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 the exam mode there is no Feedback button. However, you may still send email to the professor and TAs by using (for instance) the links on the course website's Contacts page, if problems arise on the practice test. Someone will reply as swiftly as they may. 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 haved previously submitted a correct answer, that problem's points won't appear in that particular submission, but will appear in your final total.

The exam opens at 11 AM EDT, and closes at 6:00 PM EDT, today, Thursday, 1 October 2015. After closing time, anybody may download a copy of their exam, checking the boxes for "Correct Answer", and get a PDF with his or her own solutions and the correct answers.
