Co-requisite/ Pre-requisite overrides:

• 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 (BIOL 2227 & 2227L) and enter both CRNs into the worksheet before submitting. You must register for both lecture and lab simultaneously.
• Overrides will NOT be granted for Biol 2227 (lecture) OR 2227L (lab). Biol 2227 and Biol 2227L must be taken for the first time during the same semester after which you can retake lecture or lab separately.
• 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.
• MATH 1108, equivalent math courses, or specific testing scores are also a prerequisite/co-requisite for both Biol 2227 and 2227L and must be completed by the time of registration OR you must register for all three at the same time; overrides will NOT be granted. Contact your advisor or the Office of the Registrar to check that your math course or test score was added to the Banner ERP system as a prerequisite for this course. 
• If you receive the "prerequisite or test score error" message it is most likely a co-requisite error because you are not registering for lecture and lab at the same time. You must register for both lecture and lab simultaneously. Enter the CRN for each course into the registration worksheet and then select submit. 
  

• 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.

Grades:

• Biol 2227 (lecture) and 2227L (lab) must be taken for the first time during the same semester. 
• Biol 2227 is a three-credit lecture course for which a letter grade will be awarded.
• Biol 2227L is a separate one-credit lab course for which a letter grade will be awarded.  
• If you earn lower than a 60% AND you have missed 30% or more of the semester in either 2227 or 2227L, you will receive an X grade.

• Biol 2227 and Biol 2227L must be taken for the first time during the same semester after which you can retake lecture or lab separately.
• You can register for lecture or lab separately after your grades have been finalized by the Office of the Registrar at 5:00 pm on the Tuesday after the last day of classes.
• If you have completed a course for which either 2227 or 2227L is a prerequisite, Human Anatomy and Physiology I lecture and lab CANNOT be repeated. 2227 and 2227L are prerequisites for Advanced Human Anatomy and Physiology I & II (Biol 3301/L & 3302/L).
• Biol 2227 and Biol 2227L are both introductory courses and do NOT cover the same content as Advanced Human Anatomy and Physiology I (Biol 3301/L) nor do they offer a cadaver lab experience. Any student that takes Biol 2227/2227L and skips 3301/L will be at a deficit. Students should take either; 1) BIOL 1101/L then both 3301/L & 3302/L, OR 2) 2227L then both 3301/L & 3302/L, OR 3)  Biol 2227/2227L then Biol 2228/2228L if 3301/L & 3302/L are not required by their program.

• 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.
