Resources to Succeed

This website describes recommended practices to succeed in this course, and contains a list of resources you may find helpful for a variety of issues students may encounter during your time at UW.  Contact us if you need help finding the resources you need.

One very important practice described in the above website is working collaboratively. We will create a space for you to communicate with your peers in your tutorial section and TA in a Slack channel. See Getting Started for more details.  However, you are encouraged to reach out to other students to find people with whom you can study and learn.

To organize your coursework, we have posted sample weekly schedule here. We recommend downloading it, and make your own by moving various cells (except the due dates in red cells).

Office Hours and Posting Questions

During the week the TAs and I will hold office hours on Zoom where you can ask questions.  Click Office hours for the office hour schedule. 

Use Slack or the Discussion Board for physics questions or syllabus related questions.  Students are encouraged to answer each others' questions, but I will also monitor this frequently and will respond if needed.

Contact information

For questions send an email to the instructor, (Amal al-Wahish) at with your course (Phys 122), your UW netID (the part before in your email address), and name as it appears on Canvas to your section lecturer for lecture-related questions and for personal correspondence related to grades, health issues, etc.

For Lab and Tutorial questions, please contact your TA (contact information here) or the PHYS 122 TA coordinator (Kazumi Tolich) at for questions about your TA or questions that your TA may not be able to answer.

Class components

This class consists of lecture, lab, tutorial and exam components.  You can see all the components required in a given week in Modules.

Important Note: Since each exam includes questions based on the lectures, labs, and tutorials, missing a lecture, lab, or tutorial section can have an impact on your exam performance.  You should be sure to watch all lectures, and work through any lab or tutorial that you miss as soon as possible to minimize the impact on your course grade.

Lecture components:

Before each scheduled lecture you need to complete the assigned reading (see schedule below).  The lectures include the following graded components:

  • Lecture reading quizzes (4% of grade):
    • Once you have done the assigned reading (see schedule below), complete the lecture reading quiz on MyLab and Mastering. 
    • At the end of the quarter your score will be scaled by 1.25 (but not allowed to go over 100%).
    • If you missed a lecture reading quiz due to a valid reason (family and medical emergency etc.), please contact me.
  • Lecture video engagement (4% of grade):
    • After completing the reading you need to watch the lecture video and complete the embedded quizzes before 11:59 pm on the day of the assigned reading (Monday, Wednesday, and Friday).
    • These will be graded based on engagement, not on correctness.
    • Your lowest three video quizzes will be dropped.  If you miss more than three due to a valid reason (family and medical emergency etc.), please contact me.
  • Lecture homework (8% of grade):
    • These will be due on Tuesdays at 11:59 pm, and will be based on material covered in the previous weeks reading and video.
    • You can access the lecture homework in MyLab and Mastering.

Lab components:

  • Labs (12% of grade):
    • There are eight graded lab assignments, some of which may have multiple parts.
    • Each lab assignment under "Assignments" tells you the parts to be completed in Pivot.
    • The labs are due Wednesday at 11:59 pm.  Before then you need to collect and analyze data from video experiments on Pivot and answer questions based on your work.
      • After you start any of the assignments, you can save your work and go back to it as many times as you want before the deadline, thus, allowing you to talk to peers or a TA, and then go back and finish.
    • Each lab assignment will be graded based on the following:
      • Meeting learning objectives (3 points): Questions in the lab are answered, and the answers clearly show mastery of the learning objectives of the lab.
      • Needs some improvement (2 points): Questions in the lab are answered, but some answers indicate a lack of mastery of the learning objectives of the lab.
      • Needs significant improvement (1 point): Many questions in the lab are not answered and/or indicate significant lack of mastery of the learning objectives of the lab.
      • Not completed (0 points): Significant portion of the lab is not completed.
    • If you receive 0 points, 1 point, or 2 points, you can do or redo up to 2 labs without asking for permission.  After the deadline, you will temporarily no longer be able to submit new work.  Contact your TA and they can allow you to submit late work.
    • If you need to make-up more than 2 labs due to a valid reason (family and medical emergency etc.), contact me.

Tutorials components:

The tutorials include the following graded components:

  • Tutorial pretest (1% of grade):
    • These are designed to get you thinking about your ideas on topics covered in this course.  They are graded based on a thoughtful attempt, not on correctness.
    • These become available Friday at 3:30 PM and are due on Sunday at 11:59 pm.
    • Once you start a pretest, you will have 15 minutes to complete it without the ability to pause.
    • Your lowest tutorial pretest score will be automatically dropped.
    • If you miss more than one tutorial pretest due to a valid reason (family and medical emergency etc.), please contact me.
  • Tutorial in-class (3% of grade):
    • You need to attend and actively participate in discussion at your tutorial section (QZ section on time schedule) each week to get participation credit.  Each tutorial will be graded based on the following:
      • Adequate (2 points): Actively engaged in discussion throughout tutorial.
      • Needs improvement (1 point):  Multiple periods not engaged in discussion during tutorial.
      • Missing (0 points): Did not attend any tutorial section.
    • If you cannot attend your tutorial section in a given week, you can attend another section.  A schedule of tutorials with their Zoom links can be found here (select "12x" then select "122 Tutorial Schedule").  Be sure to contact your TA to let them know.
    • Your lowest tutorial in-class score will be automatically dropped.  However, you are still responsible for submitting the associated tutorial homework on time.
    • If you miss more than one tutorial in-class due to a valid reason (family and medical emergency etc.), please contact me.   
  • Tutorial homework (8% of grade):
    • Each tutorial has homework that is due at 11:59 pm the Monday after you have worked through the tutorial.
    • For each homework, you need to upload a scanned pdf file to the Canvas tutorial homework assignment. For instruction on how to create and upload a pdf, see the Tutorial Information.
    • Only part of the tutorial homework is graded completely (8 pts); the rest is examined for completeness (2 pts).
    • If you submit your tutorial homework after it is due, there is a penalty of 1% deduction of the score for every hour that it is late.
    • If you need to submit tutorial homework late due to a valid reason (family and medical emergency etc.), please contact me.
    • Your lowest tutorial homework score will be automatically dropped.

All important tutorial information can be found under the Tutorial Information.  Once at the tutorial website select "12x" for information general to all courses in the Phys 121-122-123 sequence.  Select the link for section A or B under "PHYS 122" to get the schedule for all assignments specific to your class.


Exams will be done online.  The exam procedure is described here.

The following dates are preliminary and may change.

  • Midterm exam 1 on April 29th starting between 4:55 and 5:15 pm (PST). Once you start the exam, you will have 60 minutes to finish the exam.
  • Midterm exam 2 on May 20th starting between 4:55 and 5:15 pm (PST). Once you start the exam, you will have 60 minutes to finish the exam.
  • Final exam for 1 hour and 50 minutes. You can take either of the options below that fits your schedule better.
    • Option 1: on Wednesday, Jun 9th , starting between 2:25pm and 2:45pm (PDT)
    • Option 2: on Thursday  June 10th,  starting between 8:25am and 8:45am (PDT)

Note that there are no make-up exams.  So, students with outside professional, service, or career commitments (i.e. military service, ROTC, professional conference presentation, NCAA sports, etc.) conflicting with the exam dates must contact me early in the quarter to establish alternate examination procedures.  Exam scores for students who miss an exam without making prior arrangements will be zero.

Each exam is out of 100 points, and have three components:

  • 70 points on lecture material
  • 15 points on tutorial material
  • 15 points on lab material

Exams will count for 60% of your grade.  Your overall exam score will be based on the best of the following two methods:

  • Method 1: 20% from each of your midterms scores and 20% from your final exam score
  • Method 2: 20% from your best midterm score and 40% from your final exam score

We will design the exams such that a student who understands some of the material very well but needs some improvement in the remaining material should get a score around 65%.  If the class average on a given exam is less than 65%, then all the scores for that exam will be adjusted upward so that the average is 65%. Scores will not be adjusted downward even if the class average is higher than 65%.

If a student is found responsible for misconduct during an exam, a score of zero will be given for that exam for this student.  If the misconduct occurs during a midterm, only Method 1 is used to calculate the final grade, and Method 2 is not used.


You will get a grade of 0 for the entire course if you receive less than 16 out of the 24 points possible on the lab assignments.

Otherwise your final weighted percentage is converted to a grade point using the following thresholds.

grade point course score   grade point course score   grade point course score   grade point course score
4.0 92.0 3.0 76.0 2.0 60.0 1.0 44.0
3.9 90.4 2.9 74.4 1.9 58.4 0.9 42.4
3.8 88.8 2.8 72.8 1.8 56.8 0.8 40.8
3.7 87.2 2.7 71.2 1.7 55.2 0.7 39.2
3.6 85.6 2.6 69.6 1.6 53.6    
3.5 84.0 2.5 68.0 1.5 52.0    
3.4 82.4 2.4 66.4 1.4 50.4
