TIPS ON SUBMITTING
                 HW ASSIGNMENTS WITH WEBASSIGN

    The PHY121 WebAssign problems are designed to be
  done in STUDY GROUPS of 2-3 serious students.

    You will receive 10% bonus points for each question
  that you complete more than 48 hours before the
  assignment deadline.

    Please, never use your browser's BACK button in the
  middle of an WebAssign session.  The system is
  designed to only move in the forward direction.

    The way things are set up at this time, you will have
  four opportunities to answer each numerical part of each
  problem.  For Mutiple Choice parts, you only get ONE try.
  To have your answer graded for a single part of a problem,
  fill in only that part and select

          "Submit New Answers to Question ____".

  For numerical parts, you may simply fill in that part and
  hit the SUBMIT button.  If a part has been left blank, no
  submission is charged for that part.  Always use three
  significant figures in your numerical answers (unless the
  program gives other instructions for a particular problem).
  Numerical answers must be correct to within 2% (with rare
  exceptions which are noted within the problems).  To enter
  a number in scientific notation, use the format *.**E**;
  for example 5.97 X 10^24 would be entered as 5.97E24.

  NOTE:  There are some questions for which you have to
  "select all true statements."  These are called "Multiple-
  Select" questions; on these questions, you get the usual
  four submissions.

    As the semester progresses, and questions become
  somewhat more difficult, you may be allowed more than
  four submissions for some parts; in such cases, there
  will be a 5% penalty for each wrong answer.

  Approximately 5 minutes after the due date for each
  assignment has passed, you will find a practice version
  of the assignment available.  You may do this practice
  version as often as you like, but no credit will be
  given.  The practice versions are found by going to
  "Past Assignments", then opening each assignment.  At
  the bottom of each randomized question, you will find a
  button that allows you to practice the question as often
  as you like.  If the button doesn't appear immediately,
  just click on the answer box for that question.
