Updated 05/02/18

For the Fall 2018 term, Biology 1A and Biology 1AL will be part of a pilot program utilizing automatic course requisite checking on enrollment. As a result, some changes from the previous enrollment process are being implemented. Please read below for the details.

All students enrolling in Biology 1A/1AL are exepcted to read and understand the information provided here.

Pre-requisite Requirements:

Pre-requisites will be checked by the enrollment system at the time of enrollment. Only students who meet the pre-requisites will be able to enroll.

To meet the pre-requisites at the time of enrollment, your student records must reflect completion of the required courses (or other courses or exams determined to fufill the requirement), or that you are currently "In Progress" (currently enrolled) in the required courses (or equivalent courses). Any pre-requisite courses that are "In Progress" will be checked again by the system later to confirm completion of the requirements.

The pre-requisite courses required are, at minimum, a C- or better grade in one semester of General Chemistry and General Chemistry Lab which are CHEM 1A and CHEM 1AL here at UCB. Any other courses which are considered equivalent or greater than CHEM 1A/1AL will meet the requirement (such as CHEM 4A), but it's possible not all cases will be accounted for in the system at this time.

Transfer courses can also meet the requirement if they are entered into studetn records and there is an articulation agreement with equivalence to CHEM 1A and CHEM 1AL.

Exam Scores conferring equivalence to General Chemistry are also taken into account. These exams include the AP Chemistry Exam, the IB HL Chemistry Exam, and the A-Level and AS-Level Chemitry Exams.

The pre-requisite requirement controls are set to allow the following:

CHEM 1A and CHEM 1AL (including CHEM 1AD)


CHEM 1A and CHEM 1AL Equivalent Exams






CHEM 12A, 3B, or 12B

The higher level Chemistry course are not required pre-requisites, but they are simply used show a student has sufficinen knowledge of Chemistry even though their records may not specifically contain grades for CHEM 1A and CHEM 1AL.

Any students who meet the pre-requisites in some way that is not contained in their UCB student records will not be able to enroll until granted permission by the Enrollment Coordinator for Biology 1A/1AL. This includes any students with course credit from other schools that do not have an articulation agreement with UC, transfer course credit or exam scores which have not yet been entered into a student's records, and students planning to take courses equivalent to CEHM 1A and CHEM 1AL at another school over the Summer.

If you have been blocked from enrolling because of coure pre-requisites, but you believe you do meet the requirements (or will meet the requirements before the start of classes), you can submit a request for permission to enroll.

To request permission to enroll and provide proof of qualification, please submit this Pre-requisite Declaration Form.

AP Biology Exam credit (or any other similar exam for Biology) has no impact upon course pre-requisites.


Co-requisite Requirement:

Students are required to enroll in both Bio 1A and Bio 1AL in the same term. The courses have been set as co-requisties of each other. This means that a student will be able to enroll only if they are enrolling in both Biology 1A and Biology 1AL at the same time (in the same shopping cart). If a student attempts to enroll in only one of the two courses, this requirement will not be met and the enrollment will fail.

Students must make sure they have 5 units availble under the maximum allowed to be able to enroll. In Phase 1, students must have not more than 8.5 units of enrolled and waitlist classes already, or the 13.5 unit maximum for Phase 1 will be exceeded.

Because of the co-requisite requirement, it is no longer possible to enroll in Biology 1A and 1AL in separate phases of enrollment.


Exemptions from the Co-requisite Requirement:

There are some cases where students may be exempted from the co-requisite enrollment requirement. Some major advisors may tell students they do not need to take both Bio 1A and Bio 1AL for their major, but this does not grant any exemption from our enrollment reuirements.

Find the case below which fits your situation and use the link to the online Google form to submit a request for an exemption. The Google forms will reauire you to be signed in to your bConnected ( email account to access the form.

  1. Students who have already been enrolled or are currently enrolled in Bio 1A and Bio 1AL previously are considered to be Repeating Enrollment students. See the Repeating Enrollment section below.

  2. Students who have already completed a course equivalent to Bio 1A or Bio 1AL may submit a request for an exemption from the co-requisite requirement. Please submit the request using the Completed Equivalent Exemption Request Form.

  3. Student who have ALREADY (at the time of enrollment) declared thier major in Chemical Engineering, Mechanical Engineering, or Electrical Engineering & Computer Science may submit a request for permission to enroll in Bio 1A alone. Please submit the request using the Declared Major Exemption Request Form.

  4. For any other reason (besides repeating enrollment) students may have for requesting an exemption from the co-requisite requirement, please submit a request using the General Exemption Request Form.

Anti-requisite Requirement (Repeating Enrollment):

Biology 1A and Biology 1AL been configured with an "anti-requisite" which will block enrollment of any student who has previously been enrolled or is currently enrolled (In Progress) in Biology 1A and/or Biology 1AL.

This has been put in place to ensure that student who have never been enrolled in Biology 1A and Biology 1AL have first priority to enroll. Students who wish to repeat the courses cannot enroll unless given permission by the Enrollment Coordinator.

Permission to repeat enrollment will not be granted during Phase 1 of enrollment.

Depending upon conditions, permission to repeat enrollment may not be granted until the first week of classes for the term.

To submit a request for repeating enrollment in Biology 1A and/or 1AL, please use the Repeating Enrollment Request Form.

Error Message:

The enrollment system will respond with the same error message if any of the three requisite conditions is not met (pre-requisite, co-requisite, or anti-requisite). The message displayed should now read:

Error: Unable to add this class - requisites have not been met.

CHEM 1A+1AL (C-), CHEM 4A (C-), AP Chem (4), IB HL Chem (5), or A-Level Chem (C); Coenrollment in Biology 1A; BIOLOGY 1AL cannot be IP or previously passed. If requisites are met, the problem could be that enrolling in 5 units exceeds maximum allowed.

If this message is received, confirm the following before requesting help:

1. The enrollment request was for both Biolgoy 1A and Biology 1AL at the same time.

If this is the case, try again with both Biology 1A and Biology 1AL classes added to the same cart.

2. Confirm that enrolling in 5 more units will not exceed the maximum allowed at the time of enrolled and waitlisted classes.

If this is the case, drop classess to make more space and try again with both Biology 1A and Biology 1AL classes added to the same cart.

3. Confirm completion or "In Progress" status at UC Berkeley of the Chemistry pre-requisites.

If this is the issue, use the Pre-requisite Declaration Form to submit proof of qualification and request permission to enroll.

Unfortunately, the system will not generate an error message stating that enrollment will exceed the maximum units allowed in this case. So it's necessary to consider all the possible options which could be resulting in the enrollment error carefully.


Exams scheduled in the evening for other courses could conflict with the Monday 5:00-6:30pm lectures and Tuesday 6:30-9:30pm lab sections. Students are to make sure they are able to attend all class meetings and exams. Time conflicts with other classes will not be accommodated. Check the notes on the Class Schedule listings for any information about exam schedules. Make changes to your schedule as soon as possible when you find about any conflicts.

Bio 1AL has exams scheduled outside normal lecture class times. The exam dates and times will be noted in the Course Notes, on the bCourses sites, and in the course syllabi. While these exams are subject to change, students must ensure they have no conflicts with the exam times as make-up exams are not possible.


Waiting Lists:

The wait lists will not be opened until the class enrollment gets close to the the enrollment limit. It is not a good idea to depend upon the wait list to get into a specific lab or discussion time as a student can only be on the waitlist for one section at a particluar time. Check back frequently for open seats in other sections at the same time or other times that work in the schedule.


Concurrent Enrollment (UC Extension):

Concurrent Enrollment in Biology 1A/1AL is possible only if there are seats open in the courses at the beginning of instruction for the term after all registered student enrollments have been confirmed. As it cannot be known until the begining of instruction what seats may be available, it is not possible to approve concurrent enrollment any earlier.

To inquire about Concurrent Enrollment, please send email to Erol Kepkep, the Biology 1A/1AL Enrollment Coordinator, at
