This is a summary of a few﻿﻿ questions from yesterday and﻿﻿﻿﻿﻿﻿﻿﻿ my responses.

1. ﻿ Zoom invitation for Wednesday﻿﻿ 
I still have to send this in a separate message.  If all goes well there will be an invitation for tomorrow at class time.﻿﻿﻿﻿﻿﻿﻿﻿﻿﻿﻿﻿﻿﻿﻿﻿﻿﻿﻿﻿﻿﻿﻿﻿﻿  Otherwise the format will be the same as yesterday with an expected start in Zoom sessions on Friday.
2.  What to read
The first things to go through are the documents posted to Syllabus on iLearn.  Next comes  http://math.ucr.edu/~res/math153-2019/history00.pdf in the course directory.  I will have more to say about the other documents for unit 0 when Zoom sessions start.
3.  Grading for exams
Normally my grading is along a curve which varies from one exam to another based upon student performance.   My grading is meant to reflect how well students have mastered the material in a qualitative way.
4.  Attendance
Attendance is not taken, but students are responsible for knowing what is covered in class.
5.  Course textbook requirement
Much of the course material is in the course directory, but the textbook contains required readings  and problem assignments.  As indicated in the announcements, I'm very unhappy with the normal retail price of this book so I suggest trying to get a copy from some alternative (legal) source.  A used copy is fine, and one can even use the 6th edition for almost everything (but I may not be able to provide page to page conversions from the most recent edition to older ones).  
6. More clarity on the structure of the quizzes and exams. Will the be free response? Multiple choice? Will there be computation involved or just history based concepts?
In the past the exams have been mostly problems reflecting the various time periods together with some questions on historical information.  I plan something similar, but the online format of the course will force some modifications which I will explain after I have made decisions. 
7.  Will we have assignments outside of quizzes and exams or is it just keep with the readings for the exams?
Recommended homework assignments will be posted but not collected.   The point of quizzes has been to act as a substitute for homework in several respects (periodic feedback, incentive not to fall behind, etc.).  Solutions for all assigned problems (and others) are or will be posted.
(Related answer)  Homework will be assigned but not collected; solutions are posted for the problems.  If additional problems are added then additional solutions will be posted.   Lists of recommended problems will be posted in Update files.  Examples from last year are in the course directory.  
8.  When are we supposed to know which  "EXERCISES RELATED TO history0X" we should be attempting through the weeks?
These will be announced as the quarter progresses.  In the meantime the files aabUpdate*.153.s19.pdf might be helpful.  Solutions are posted, and homework will not be collected.
9.  For discussion sections, are they going to be held at the time listed on Banner or are they pre-recorded and posted on iLearn? Also, are your lectures going to be pre-recorded and posted or are they going to be presented live? 
All class sessions are to be live or semi-live at the scheduled times; there is a directive from the Campus Administration about this.   Normally there will be Zoom or Piazza sessions or the instructor will be watching his computer in order to answer email right away.  The third option is what I used yesterday, and I am going to summarize some of the questions later today.   There is also a good chance that there will be a Zoom invitation for tomorrow but that is not yet confirmed.   As is always the case, individual meetings might be cancelled if the instructor has reasons to do so, but the default is that things will be live.  Right now I am inclined not to make recordings of sessions, but that could change if circumstances warrant doing so.
