This document has some specific information about the exam: the content, type of questions, etc.

I will ask you to do a course evaluation. I will give it to you after the exam; you can do it over winter break.

Upcoming Events

Check the departmental colloquium schedule. You should come to these talks. They are typically Friday at 12:30 in Rm. 199, and include free pizza.

There are telescope public viewings the second Tuesday of each month, at the Peter van de Kamp Observatory on the roof of the Science Center. The next one is on January 14, at 8 PM. Astro 16 students are welcome to come and help out. It is also an excellent opportunity to show your friends the observatory and the view of astronomical objects through our telescope.
