Video recordings of our past classes are available to registered students via [https://umb.umassonline.net/webapps/blackboard/content/listContentEditable.jsp?content_id=_1326069_1&amp;amp;course_id=_22123_1&amp;amp;content_id=_1326409_1 Blackboard].&lt;br /&gt;

&lt;br /&gt;
Weekly quizzes happen on Mondays, starting at 10:40 a.m., and are due by 10:50 a.m.  (During weeks when Monday is a holiday, the quiz happens on Wednesday.)  They are hosted on a [https://umb.umassonline.net/webapps/blackboard/content/listContentEditable.jsp?content_id=_1329797_1&amp;amp;course_id=_22123_1&amp;amp;mode=reset folder within our Blackboard site].

I also recommend that you remain signed in to our Zoom session while taking the quiz.  I will remain in the meeting in case you have any questions.  &lt;br /&gt;
&lt;br /&gt;
==Exam link==&lt;br /&gt;
&lt;br /&gt;
There is a [https://umb.umassonline.net/webapps/blackboard/content/listContentEditable.jsp?content_id=_1329900_1&amp;amp;course_id=_22123_1&amp;amp;mode=reset separate Blackboard folder for exams].  On exam days, please sign in to Zoom at least five minutes early with your video on, make sure you have photo ID available to hold up to the camera if requested, and click over to the Blackboard folder in another tab.  The exam will appear at the official start time of the class.  You will work each question on paper, then scan or photograph your work and upload the resulting image file as your response.  More detailed exam instructions will be sent by e-mail as the exam dates approach.&lt;br /&gt;
&lt;br /&gt;
==How to use this page==&lt;br /&gt;
&lt;br /&gt;
Below you will find links to the weekly assignment pages.  Each of these pages is editable by anyone in the class, so apart from telling you what problems to work on they are excellent spaces in which to ask questions.  (If you are very shy you may ask your questions privately, either by [mailto:Steven.Jackson@umb.edu email] or in person.  But we will all work more efficiently if you ask them on the wiki, so that each question only needs to be answered once.)  It is also extremely helpful to try to answer questions posed by other students.  I will monitor these pages to ensure that no wrong answers go uncorrected.&lt;br /&gt;
&lt;br /&gt;
If you are not already familiar with them, you may wish to read about [http://en.wikipedia.org/wiki/Help:Wiki_markup wiki markup] and [http://en.wikipedia.org/wiki/MOS:MATH#Typesetting_of_mathematical_formulae typesetting mathematics].  Also, you may wish to add this page and the assignment pages to your [[Special:Watchlist|watchlist]] using the link in the upper right corner of each page, then change your [[Special:Preferences|preferences]] to enable e-mail notifications; this way you will know about page activity without constantly re-checking all the pages.&lt;br /&gt;
&lt;br /&gt;
