NO MAKE-UP MIDTERMS OR FINAL WILL BE OFFERED UNDER ANY CIRCUMSTANCES, EXCEPT IN CASES WHERE A SCHOOL APPROVED INCOMPLETE IS WARRENTED.

If you miss a midterm for any reason (e.g. illness, sporting event, funeral, wedding), that midterm will be dropped and the final exam will be weighted at 40% of your overall class grade. Any additional missed midterms will not be replaceable.

You must take the final to pass the class.

If you take all the midterms and score higher on the final exam than your lowest midterm score, then your lowest midterm score will be dropped and the final exam will be weighted at 40% of your overall class grade.

Quiz Guidelines


  • All quizzes are administered through Canvas.
  • You have a 12-hour window (9:00 am and 9:00 pm) to complete each quiz. Start early enough to finish by the deadline.
  • Each quiz is timed at 30 minutes.
  • Quizzes include both short answer and multiple-choice questions.
  • No partial credit is awarded for incorrect answers.
  • Use only the exam information sheet, calculator, and scratch paper during quizzes.
  • If a quiz is not completed by its due date, you can still view the questions and answers on Canvas.
    • Click on the quiz.
    • DO NOT ANSWER ANY QUESTIONS; simply hit submit to see the correct answers.
    • Answering after the deadline results in a quiz score of -2 points.

Midterm and Final Guidelines


  • The midterms and final exam will feature short answer and multiple-choice questions.
  • No partial credit is awarded for incorrect answers.
  • Exams are graded and returned via GradeScope: gradescope.com
  • Calculators are permitted during exams.
  • An exam information page, including the periodic table, constants, unit conversions, and equations, will be provided.
  • Bring your student I.D. (or another government issued I.D.) to the final exam.
  • Looking at a cell phone during the exam results in an exam score of 0 that cannot be dropped.
  • Sitting next to someone with the same version of the exam, incurs a penalty of 5 points.
  • Headphones are NOT allowed during exams.
  • Continuing to work on your exam after time is called, incurs a penalty of 5 points.

Homework


  • Online homework will be assigned through ALEKS (aleks.com). Your ALEKS course code for this class is: K3J4U-HNQJD.

      • Select "Use remaining time from …"
      • Verify your perm number by navigating to "manage my classes" through the ≡ icon (3 bars) in the upper left corner of the screen. Click the down arrow next to your name and select "account settings." Click "edit" next to your school and check and change your perm number, if needed.
  • INSTRUCTIONS IF YOU DO NOT HAVE AN ALEKS ACCOUNT:
    • Open a web browser
    • Go to aleks.com
    • Click on "SIGN UP NOW"
    • Enter the course code: K3J4U-HNQJD

  • Each pre-chapter assessment is worth 1.5 points.
  • Up to 7 points from these assessments can replace your lowest ALEKS score.
  • Do not consult external resources for these assessments; you are only graded on completion, not accuracy.

Support for Students in Distress


  • Personal concerns such as stress, anxiety, relationships, depression, or cultural differences, can impact students’ ability to succeed and thrive.
