General Overview

All students who register in CHE 2A or CHE 2AH are required to satisfy the Chemistry Placement Requirement. Students who do not satisfy the placement requirement to remain enrolled in general chemistry will be administratively dropped from the course by the Department of Chemistry. There are no exemptions to the Chemistry Placement Requirements.

A score of 24+ on the Chemistry Placement Exam is required to ensure enrollment in CHE 2A. For CHE 2AH, a score of 33+ is required.

Fall 2020


2020 New Student Placement Testing for Orientation

One of your first steps before enrolling in classes is determining your correct placement for your new college courses. Enrolling in the appropriate level course is critical to your success as a first-year student. New students enrolling in Fall 2020 should plan to take the online Chemistry Placement Exam prior to New Student Orientation

Many students will need to take the Chemistry Placement Exam. It is required to ensure enrollment in our general chemistry classes (CHE 2A or CHE 2AH). This exam is designed to assess your preparedness for subsequent chemistry courses. You may not be required to take the Chemistry Placement Exam depending upon your declared or intended major, the courses you wish to take, or your career goals. If you are uncertain about whether or not you need to take the Chemistry Placement Exam, it is in your best interest to take the exam for future academic options.

Over the past few weeks, the campus invited students via your UC Davis email account (or email address on file) to complete the online Chemistry Placement Exam during designated sessions according to your admitting college. If you missed your college’s initial testing session or you did not pass the exam with a required placement score (24+ for CHE 2A; 33+ for CHE 2AH), you can still take the Chemistry Placement Exam prior to the start of Fall Quarter.  Please note:

  • Fall Quarter Testing Session #1: Begins at 11:00a (PDT) on September 9 and ends at 11:00a (PDT) on September 15
  • Fall Quarter Testing Session #2: Begins at 11:00a (PDT) on September 30 and ends at 11:00a (PDT) on October 6

If you wish to prepare or refresh your understanding of basic chemistry concepts before taking/retaking the Chemistry Placement Exam later this Summer, feel free to do one or both of the following:

  • Study on your own by reviewing high-school chemistry concepts. Any "Introduction to Chemistry" text would be good for review. You may also find our Chemistry LibreTexts webpage helpful.
  • Complete the ALEKS Preparatory Chemistry Online Course, which is designed to test for individualized knowledge gaps and to fill the gaps through computerized adaptive learning software. This online preparatory option is available to all students. A new session of the ALEKS Preparatory Chemistry Online Course specific to Fall 2020 is now open.
