Links to old Math 20D exams appear below. The following exams are provided "as is"—exactly as they appeared when administered and without answers. These are NOT practice exams. They may differ in form and content from the exams given this term. Working through these old exams may be helpful, but it is not a substitute for reviewing your notes, homework, and keeping up with the class on a daily basis. They are provided so that you can know what exams in this class will look like.

  • It is your responsibility to ensure that you do not have a schedule conflict involving the final examination.
    You should not enroll in this class if you cannot sit for the final examination at its scheduled time.
  • Make-up Exams or Quizzes:  Make-up quizzes or exam will not be given, nor will we offer exams at an alternate time. If you miss a quiz for any reason, the score for that quiz will be 0.

    Late submissions and Quiz Score:  Each quiz worths 10 points. If the quiz is submitted to gradescope within 10 minutes after the deadline, 5 points of that quiz will be took off. No late submission is allowed for the exams.

    Grading:  There are two methods to determine your course grade:

    Your grade will be computed using both methods and then the better grade will be used. After your weighted average is calculated, letter grades will be assigned based on the standard grading scale:

    A+ A A- B+ B B- C+ C C- D F
    [99,100] [93,99) [90,93) [87,90) [83,87) [80,83) [77,80) [73,77) [70,73) [60,70) [0,60)

    Note on MATLAB grades:  There are four MATLAB assignments and one MATLAB quiz. Each of these five is worth 2% of your grade (for 10% total).

    There will be no curve, but we may adjust the scale to be more lenient (depending on the performance of the class). While we may adjust the scale to be more lenient, we guarantee that the grade corresponding to a given percentage will not be lower than specified by the above scale.
    No extra credit will be given in this class.

    MATLAB Assignments:   The MATLAB assignments are a required part of the course. The assignments, DUE DATES, and instructions on how to submit the assignments can be found on the Math 20D MATLAB webpage. There will be MATLAB tutors available to help you with your assignments.

    The MATLAB Quiz: There will be a MATLAB quiz given at the end of the quarter.If you are unable to make the scheduled time, you will be able to schedule an alternate time online. See the Math 20D MATLAB webpage for more information.

    Gradescope: Exam grading will be done using an online tool called Gradescope (https://gradescope.com/). Exams will be scanned and uploaded to Gradescope and will be graded within it. As a consequence, exams will not be returned to the students. Instead, a digital version of your exams will be made available after the grading has been completed. An email will be sent from Gradescope when the exams are made available.

    Regrades:  Regrade requests will be made using the built-in regrade request feature in Gradescope. There will be a limited window of time after the exams are made available during which the regrade request feature will be active. This time window will be announced when the exam (quiz) scores are released to the students.

    Academic Dishonesty:  Academic dishonesty is considered a serious offense at UCSD.  Students caught cheating will face an administrative sanction which may include suspension or expulsion from the university.  It is in your best interest to maintain your academic integrity.
