Department of Chemistry and Biochemistry COVID-19 Undergraduate Updates

If you do not find the answer to your question below, please feel free to reach out to the Department of Chemistry and Biochemistry via the Virtual Advising Center (VAC).

Additional updates to university deadlines and policies can be found here:


WI21 CHEM 6A, 6B, and 6C Help Room has been cancelled. Help with general chemistry is available through your Teaching Assistants' office hours, as well as the resources found here.


Pass/No Pass Policy

The Department of Chemistry and Biochemistry is pleased to announce that all Chemistry/Biochemistry majors and minors will be allowed to use “P” grades to fulfill major or minor coursework taken in the Spring 2020, Fall 2020, Winter 2021 and Spring 2021 terms. 

IMPORTANT NOTE: All major classes taken in Summer 2021 and Fall 2021 must be taken for a letter grade. P/NP grading is not acceptable for major classes taken in Summer 2021 and Fall 2021.

Please note the following:

  • This policy applies for all lower-division and upper-division coursework required for your Chemistry/Biochemistry major or minor taken in Spring 2020, Fall 2020, Winter 2021 and Spring 2021.
  • “P” grades do not count towards your GPA and a 'C-' or higher is required to earn a "P". More information can be found on TritonLink.
  • Spring 2020, Winter 2021 and Spring 2021 courses are excluded from the 25% limit on P/NP units, per the Academic Senate.  Courses taken P/NP in Fall 2020 are counted towards the 25% limit. See details here.
  • The Department can only confirm the P/NP policy for majors and minors in the Department of Chemistry and Biochemistry. If you have questions about the P/NP policy for general education requirements, please contact your college's advising office.
  • Some graduate and/or professional schools may not accept courses in which a “P” grade is received (i.e. some schools may require letter grading).  In this case, we recommend reaching out to schools you wish to attend to inquire about their admission policies. 

Please see the most recent COVID-19 updates from the Academic Senate here.


Lab Courses

Lab course offerings: All SP21 labs (CHEM 7L, 43A, 100A, 100B, 105A, 108, 109, 123, and 143B) will be offered in remote format only.
Lab fees: SP21 lab fees will be refunded by the registrar's office during week 3 of the quarter. The refund will go to your student account. If you do not receive your refund by Monday, April 12th, please contact
Lab Drop/Safety Exam Policy: Although the 1st day administrative drop policy for laboratory courses is not being enforced during remote format, the lab safety exam requirement remains. Students are required to pass a laboratory safety exam for each Chemistry or Biochemistry laboratory course on their schedule, or risk being administratively dropped. Safety exam information, study materials and the exam can be found on the course safety training Canvas site "Chem XXX - Lab Safety Training - Instructor [SP21]." The deadline for passing the Sp21 lab safety exam is 11:59pm Tuesday, March 30th, 2021
Note: Waitlisted student who are added to the course after the start of instruction will be given an alternate testing window during which they must take and pass the lab safety exam.

Course Formats (In-Person, Hybrid, Remote)

While most courses in the Department of Chemistry and Biochemistry will be offered remotely, there are currently several discussion sections that will be offered in a remote or hybrid format. We highly recommend periodically checking the Schedule of Classes to get the most up-to-date course classification information. Please note that courses in the Department of Chemistry and Biochemistry are subject to change from hybrid to fully remote, dependent on the state of the pandemic. Please continue to check the Schedule of Classes to receive updated information.

For questions about asynchronous & synchronous instruction, please contact the instructor directly. Do not assume that a course will be taught asynchronously as this information will need to be confirmed and provided by the instructor. For further information on WI21 course formality, please refer to the Winter 2021 Schedule of Classes FAQ page.

How to read the Schedule of Classes:

RCLAS = Remote class

Courses labeled RCLAS are operating remotely. Make sure to check both lectures and discussions. If both lectures and discussions list RCLAS this course is fully remote.

HYBRID = Part remote, part in person

Courses that are operating as a hybrid, or part remote and part in person, indicate the remote section using RCLAS and a room number for the component that is in person. For example, if Chem 6A A00 lecture lists RCLAS but A01 indicates the discussion in York Hall, this is a hybrid class.

In Person

There are no fully in person courses scheduled at this time.
