The General Chemistry Placement Test is for students who want to enroll in CHEM 1402- General Chemistry I and **did not** have a minimum score of 24 on the science reasoning section of the ACT. Students must pass the CHEM 1402 Placement Test with a grade of 60 or higher.

## Placement Test Details

- The test consists of 40 multiple choice questions (20 math questions and 20 chemistry questions) that must be completed in 40 minutes
- Students with appropriate documentation from the Disability Resource Center will receive extended time.
- You will be provided a non-graphing scientific calculator to use on the test.
- Each student can attempt the placement test twice per semester with a gap of at least one week, in order to be eligible to take the test the second time in the same semester.

The test is administered at Testing Services, in room 315 in the Student Services Center. You can register for the test online.
