• Co-requisite Required - The course you are trying to enroll in has a co-course requirement.  You must concurrently enroll in both courses at the same time.  Find the CRN for both courses (example: BIOL 1101 & 1101L) and enter both CRNs into the worksheet before submitting.
• Overrides will NOT be granted for Biol 1102 (lecture) OR 1102L (lab). Biol 1102 and Biol 1102L must be taken during the same semester even when retaking the course (see section F). Once you have added yourself to the wait-lists for lecture and lab, you will need to wait until you have received automatically generated ISU email notifications (one for lecture and one for lab) telling you that you can register.

• The class is full.
• Please follow these directions:
  1. Add yourself to the wait-list. Instructions for wait-listing can be found at: Office of the Registrar > Class Registration Info.
  2. Wait for an automatically generated email notification (sent to your ISU email account) telling you that you can register.
  3. Check your detailed class schedule in MyISU, Registration Landing page for your position on the wait-list.
• If you are unable to add yourself to the wait-list it means that the wait-list is full. Check MyISU daily to see if you can add yourself to the wait-list.

• This means that we cannot put you into a lecture or lab section or register for you in any way.
• Your name must reach the top of the lecture and lab wait-lists before you will be allowed to register.
• Please check your ISU email for an automatically generated ISU email notification telling you that you can register once you have added yourself to the wait-list.
• Enrollment numbers cannot be increased for any lecture or lab sections including the online lecture.

• Biology faculty/instructors/staff CANNOT help a student switch/swap sections.
• Drop the section for which you are registered and add another section that fits your schedule. If you are on the wait-list for a different section of a class you are already registered for, you must drop the other section before you can add the new section. For more information please visit: Office of the Registrar > Class Registration Info > Add/Drop/Swap Courses.
• Remember you need to add and drop at the same time or you will be dis-enrolled from lab AND lecture.

• You must take the full Biology II course (BOTH Biol 1102 and 1102L) again.
• If you have completed a course for which Biology II is a prerequisite, Biology II CANNOT be repeated.

• You can register for/attend lecture and lab on different campuses.
• The lecture begins the FIRST week of classes.
• Laboratories begin the FIRST week of classes and there is MANDATORY ATTENDANCE. It will be considered an UNEXCUSED ABSENCE for the first lab (i.e. Lab 1) if you;

1. do not attend the laboratory for which you are registered,
2. register after labs have begun, OR
3. attend a lab section for which you are not registered although you are registered for another section.

• If you are unable to attend the first week of the lecture and lab because of an ISU sponsored activity, please contact the lecture instructor and the lab coordinator.
• If you are close to the top of wait-lists for lecture/lab, it is recommended that you attend both lecture and lab. Please contact the lecture instructor and the coordinator before the first lecture and lab so they can give you access to the assignments.
