The Chemistry Department has many courses for which the laboratory is co-requisite with the lecture.

This means for any of the above courses, you must take the lecture and lab at the same time. The only time the Chemistry Department allows students to take one without the other is if they have attempted both courses before and failed one of them.

The notorious “Prerequisite/Test Score Error” message (arrrrgh!)

Registering for co-requisite courses in OneStop/Banner is a little tricky. Often students will try to add the lecture and then add the lab only to have OneStop/Banner reject it as a “pre-requisite/test score error.” This is because the system reads the student as trying to register for only the one half of a pair of co-requisite courses. Banner does not have a “co-requisite error” code, so it labels it a “pre-requisite error.”

You must enter the two courses at the exact same time. To do so you must use the Add/Drop page. Take the CRN numbers from the OneStop semester catalog (the number in blue along the left hand side) and enter both CRNs in the boxes at the bottom of the page (see graphic below). Then click “Submit Changes”. 

The Add/Drop page:

Note: Since MATH 1065 is a prerequisite or co-requisite of CHEM 1150, if you have not taken it before you will need to type in the CRN of this course either before or along with those for CHEM 1150 and 1151 (there are several boxes into which you can type CRNs on the Registration page, so there is plenty of space to put the CRNs for all three classes before submitting the changes).

If you continue to have difficulties registering, make sure:

1. The classes have available seats. This information will be listed in OneStop. See below:

Our labs are set up to have a set number of stations. Not only is it impossible for two students to share the same lab station, we cannot exceed those numbers for risk of violating safety codes as outlined by the Fire Marshal. Once a lab is closed it is closed. We cannot special add students to labs. If no labs have open seats, you cannot register for the corresponding lecture. In this case, please enter you name on the waitlist for the closed course. When you are notified there is a space available, you will be able to register for both lecture and lab. 

If there are seats available in both lecture and lab and you are still encountering difficulties, check:

1. There are no time conflicts in your schedule with the classes you are trying to register for.
2. That you have completed and passed the pre-requisite courses.
3. You are taking a course within your class range. For example: A freshman or sophomore should not be trying to register for a 4000 level seminars or research hours without special permission of the instructor.

If you have satisfied these requirements and are still having difficulty registering, contact Jenny Burnham at burnhamj@ecu.edu with your Banner ID number and the course, section number, and CRN of the classes you are trying to register for. She will get back to you within 24 hours to assist you.
