Chemistry Placement Testing
Chemistry placement testing ensures students have a chance at success in Chemistry 121 and beyond.
Testing is free and is done in ALEKS, an adaptive learning system. ALEKS quickly determines your current knowledge in areas necessary for success in general chemistry.
- Chemistry placement testing is only required for on campus students.
- Depending on your current knowledge, the initial knowledge check assessment will have up to 30 questions.
- The placement test is not timed, but you should plan between 60 - 90 minutes to answer these initial questions.
- You may log out and log back in again, which means you can take breaks.
- It is recommended that you have a calculator and scratch paper available.
- You should work alone on the placement test and if needed, in the ALEKS "Learning Mode". If you get help, you may be passed over for resources that will help you to succeed in your first chemistry course.
- When signing up to take the placement test, please use your unique seven digit UND student ID number not your social Security number.

Once you complete the initial knowledge check assessment, ALEKS provides a "score" that represents the percentage out of 85 topics you have mastered. A minimum score of 50% is required to register for Chemistry 121/121L.
Using your ALEKS Score to Determine Which Courses to Take
Once you complete the initial knowledge check assessment, ALEKS provides a "score" that represents the percentage you have mastered our of 85 topics. A minimum of 50% is required to register for Chemistry 121 lecture and Chemistry 121 Lab. If you score below 50%, you can improve your score by working in the ALEKS "Learning Mode" until you reach the 50% mark. Once you meet the minimum requirement of 50% (before the add/drop date), you can register for Chemistry 121 and Chemistry 121 Lab.
If you score less than 50% (which includes work in the ALEKS "Learning Mode") prior to the add/drop date, you are required to register for Chemistry 121 Recitation (121R) along with Chemistry 121 lecture and Chemistry 121 Lab. The recitation section (121R) is meant to help you practice course topics and have a greater chance of success in Chemistry 121 lecture.
