FAQs and answers for ASTR 2
---------------------------


Here are some answers to a sampling questions we've been receiving so far:

1. ?

A: *Before* you even ask a question, check the course website at:
       http://www.ucolick.org/~raja/astr2/
Most questions we've been receiving so far -- e.g., when are the discussion
sections?  how many per week? what you need if you didn't attend the first
class? etc. -- are already answered on the website.  The second resource to
check for supplemental information is the eCommons site (you must already be
on the eCommons site or the course website if you're reading this!).  Look 
around first.  While we're happy to answer questions, there's well over 100
of you and only a couple of us, and that too with busy schedules.  We've
tried to compile as much relevant information as possible in the two sites
above and would much rather answer questions about course material instead
of course logistics, so please read before you pull the trigger on email.


All that said, here are some questions and answers:
----------------

2. Which edition of the book and homework software do I need?

A: The book: *Any* edition will do: new or used, full text or custom edition
etc.  Just get the one that makes sense for you financially.

Homework software: For the online homework, however, *only* the Connect
software associated with the latest edition of the e-book will work.



3. Where/how can I borrow a book?

Please talk to one of the two TAs.



4. Can I use the iClicker app (for iOS and Android) and/or a physical remote?

A: We have the latest iClicker Cloud software. Both the app and the remote
should work. Please choose one of the two and stick with it throughout the term.
Please let us know ASAP if either system is not working for you. We can put you
in touch with the iClicker tech department folks who can help you troubleshoot
the problem.



5. I am number X on the wait list. Should I wait to see if I will get in?

A: This is entirely your call. Conservatively, anyone with a wait list number under 5
should get in but we obviously can't guarantee anything.



6. How much math will there be in the class?

A: The math is not college level - mostly single variable algebra (solve for
the one unknown quantity in an equation) and some trigonometry.  Comfort with 
powers of 10 is a good thing because we're dealing with umm, astronomical
numbers here.  That said, we'll practice in discussion sections.  Please come
to these if you feel you're rusty or uncomfortable with the above and we will
help you out.



7. Discussion sections - when, where, how many?

A: Check the class web page for the discussion section time and location.
Attending discussion sections is entirely OPTIONAL.  If you can't come to the
sections, please come to the TAs' and/or my office hours or arrange to meet us
by appointment.
