    Course Grade Breakdown
    Homework will be 30% of the total grade (there are 11 total assignments and the lowest score will be dropped), lecture participation using i>Clickers 5%, discussion attendance 5%, and exams will count for 60% (two mid-term exams are worth 15% each, and the final exam is 30%).

    Homework due dates and time
    Homework assignments are due at 6 PM on Friday. Your solutions are to be deposited in the course homework box that is located on the second floor of Loomis Lab, at the entrance to the overpass to the Materials Research Lab (MRL) on the north side. Assignments which are late, but handed in by the following Monday at 6 PM will lose 20%. No late assignments will be accepted after Monday at 6 PM!

    General Policy Regarding Grading
    Homework is considered essential to learning course material, and should be treated as training for future work rather than as a test of what you already know. You should start working on an assignment early, close to when it is posted on Friday. We encourage students to work together, and get help from the professor or TAs when they encounter difficulties. We will happily explain difficult concepts during office hours and check your work for errors. For this reason, scores on homework are typically high (~95%). Don't make the mistake of starting your homework the day before it is due!

    Partial credit will be given on homework and exams if and only if the work is coherent. A random scattering of thoughts will not be awarded points. Simple numerical errors will not be strongly punished, however students are expected to be careful about their work and will lose points for errors which give incorrect physical results. The steps to receiving partial credit are: (i) write your solution neatly and coherently using equations and words to describe what you are doing (ii) checking your answer for consistency e.g. are units correct, does the solution behave correctly in known limits? Write as though you are explaining the problem to somebody who doesn't already know the answer! Expect the exams to be challenging but to be curved accordingly.
