Grading


Quizzes (10/8/25, 10/29/25, 11/17/25, & 12/5/25)

* Up to 10 iClicker points can replace one quiz score.

4 @ 6 pts 5%
Midterms (10/17/25, 11/3/25, & 11/24/25)
3 @100 pts 56%
Final Exam (12/12/25 / 8:00-9:00 am) 1 @ 100 pts 19%
Homework Assignments

* Lowest homework score will be replaced with up to 5 points earned from pre-chapter assessments.
* ~50% of your homework grade will come from the percentage of the pie you finish (34 pts).
* The pre-course assignment is worth 10 points and cannot be replaced.

1 @ 10 pts
7 @ 5 pts
34 pts pie
15%

Discussion Section Attendance

* You can miss up to 3 discussion sections (depending on when holidays fall) without it negatively affecting your grade.

7 @ 4 pts 5%


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

If you miss a midterm for any reason (e.g. illness, sports event, funeral, wedding, etc.), that midterm will be dropped and the final exam will be weighted at 38% 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 38% of your overall class grade.

Discussion Sections


  • You must attend the discussion section you are signed up for.
    • Bring your calculator and a constant sheet to each section.
  • Before coming to section, spend 30 minutes working on the week's assigned problems (found on Canvas). It's okay if you don't finish all the problems.
  • You can earn up to 28 points for discussion sections.
    • Up to 4 points can be earned for each section.
    • 1 point is awarded for coming prepared, which requires showing the work completed before attending.
    • 3 points are awarded for attendance:
      • Deduce 1 point if you arrive late or leave early.
      • No points will be given if your presence is less than 25 minutes.
  • During discussion sections, 15 minutes will be given for comparing work with the other students. In the remaining time, the TA/LAs will go over select problems.
  • If there's a holiday on the day of your discussion section, you should still complete the assigned problems. Your TA will provide solutions afterward.

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 penalty of -2 points.

Midterm and Final Exam Guidelines


  • The midterms and final exam will feature both 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 or using 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.

  • Each pre-chapter assessment is worth 1 point.
  • Up to 5 points from these assessments can replace your lowest ALEKS score, excluding the pre-course assignment.
  • 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.
  • If you find yourself in a distressing situation and wish to speak with someone confidentially, consider the following free options:
