# Ay 123 Course Policies

September 2013

Richard Ellis

## Homework Policy

Because solving problems is the best way to
understand the material, you should attempt to
solve problems first on your own. You may consult
books and published papers, but not old homework solutions
from this class. After that,
discussion of the problems with other students in this class
to improve your understanding of the underlying
physics is permitted and encouraged, but not solutions
to the problems themselves.

In addition, because looking at your solutions is
one way for us to know how well you've learned the
material, you should work out your own solutions
without using or referring to the solutions of others.

Thus on problem sets, the formal policy for this class
(Ay 123) is that the students can freely discuss the problems,
but need to work out solutions on their own and not
refer to others' solutions.

Homework will be posted on Thursday of each week, and is due
at 5:00 PM on Monday of the second following week (11 days later).
Please hand the homework
in to the TAs either in person or in their mailboxes (MC 249-17).

## Grading Policy

Ay 123 will have a midterm oral examination conducted by
R Ellis, and a final written exam, in addition to the weekly homework
assignments.

The midterm oral will replace the homework assignment of week 5 and will
assess the student's knowledge of the first 5 weeks of the course.

The written exam will cover the entire course and be scheduled during the
period Dec 11-13. Unlike on homework assignments, no collaboration will
be permitted.

Your grade will be based 40% on the final exam, 30% on the midterm oral
and 30% on the homework.
