    EXAMS:     I : Tue Sep 28 ?     II: Thu Nov 4 ?     FINAL: Dec ??? ,
    Final Exam: it will be comprehensive and it can help you a lot:
              it will replace the lowest of your two exams, if to your advantage.
    Quizes will be given roughly every other week, with at least one class notice
    Course Grade = { Q + I + II + F } / 4
              Borderline cases will be decided according to interest shown in class and performance on the Final.
    NO MAKE-UP EXAMS WILL BE GIVEN: If, due to unforseen, dire circumstances, you have to miss an exam,
    you must notify me before the exam and then your score on the Final will substitute the missing grade.
    All incidents of academic misconduct will be reported to the Student Judicial Affairs office.
    Some suggestions for studying:
  • Do NOT miss class.
  • Read over the material before it is covered in class.
  • Listen carefully while it is presented in class.
  • Now STUDY it carefully, trying to understand the concepts and ideas involved,
      not merely "how to do it". Learn the definitions.
  • Work out as many problems as possible, at the very least the ones assigned;
      Mathematics can be learned only by doing it !
  • Get your questions answered before too many accumulate.
      Ask questions. No question is too dumb to ask.
  • Try very hard not to fall behind; it is always very difficult to catch up.
  • DO NOT hesitate to ask questions and seek help.
  • Do not hesitate to came talk to me if you are facing difficulties.
    !!! GOOD LUCK !!!
