​Chemistry Diagnostic Exam 

UPDATE:  Due to the campus closure, the Chemistry Diagnostic is not available at this time.  Please see a counselor​ for more information about a matriculation appeal. ​

The Chemistry Diagnostic Exam is for students who have already taken chemistry courses and would like to validate Chemistry 2A to enroll directly into Chemistry 1A. To be approved to take the Chemistry Diagnostic, students must provide the following documentation to a Norco College counselor, or counseling staff:

  • Completion of one-year high school chemistry with a final grade of "C” or better. (Unofficial and official transcripts are acceptable; unofficial online transcripts must be verified by a Norco College counselor or counseling staff.)
  • Completion of a 4-unit college-level chemistry course with a "C" or better; inside or outside the United States.​

Once you have your approval form signed by a counselor, you will be able to schedule your appointment to take the exam via phone, email, or in-person. You will need to bring in your signed approval form to be collected by an Assessment Staff on the day of the Chemistry Diagnostic Exam.
