TIPS ON SUBMITTING
                 PHY 121 MC TESTS WITH WEBASSIGN

    The tests consist of about 15 multiple choice (MC)
  questions.  Some of the questions may have more than
  one part.  There is only one submit button for the
  entire test; it is located at the bottom of the test.

  YOU MUST CHOOSE YOUR ANSWER FOR ALL PARTS OF ALL 15
   QUESTIONS BEFORE HITTING THE SINGLE SUBMIT BUTTON.

    There will be a 75-minute time limit.  A timer will
  appear in the upper right-hand corner of your test
  screen; you may hide the timer by clicking on it.
  If your time runs out, then your test will be submitted
  automatically.

                PRACTICE QUIZZES AT WEBASSIGN

    For each MC test, there are a set of practice quizzes
  available at WebAssign.  These are for practice only;
  there is no credit for completing them, and no penalty
  for omitting them.  These quizzes consist of a mixture
  of MC and numerical questions which will give you another
  test of your conceptual understanding and problem-solving
  skills prior to the test.  Once you have selected an
  answer to a quiz question, a submit button will appear
  for that question.  THIS IS UNLIKE OUR MC TESTS WHICH 
  WILL JUST HAVE A SINGLE SUBMIT BUTTON AT THE BOTTOM OF
  THE SCREEN.  Quiz questions allow multiple submissions
  (unlike MC test questions), and after four incorrect
  submissions, WebAssign will show you the correct answer.
