Enrollment Requirements

Prerequisite Requirements:

To be enrolled in Biology 1A and/or 1AL, students must have completed both Chemistry 1A (or 1AD) and Chemistry 1AL with a C- or better grade. Any other course(s) or exam which confers equivalence to Chemistry 1A(D)/1AL (fulfills prerequisites, at minimum, for enrollment in Chemistry 3A and 3AL courses are acceptable (such as Chemistry 4A, courses from another school, a 4 or 5 score on the Chemistry AP test, sufficient score on the IB HL Chemistry exam, etc.). Chemistry 3A or 12A (formerly 112A) are recommended.

For equivalent courses from other schools or exams, documentation of grades/scores in those courses/exams must be provided. The equivalent courses must fulfill the requirements to enroll in Chemistry 3A and 3AL to apply (both the lecture component and lab component must be completed prior to the start of Summer classes). AP exam credit is available to us within the student records for UC Berkeley students, but the score received is not readily available.

Students who do not (or will not prior to the start of classes) fulfill the prerequisites are not to enroll. Students who have not completed the minimum chemistry prerequisites by the beginning of the semester may be dropped from enrollment at any time.

Students must have already received a passing grade in the prerequisite classes prior to the beginning of class instruction for the enrolling term. Students enrolled in Chemistry 1A(D)/1AL (or 4A) at the time of enrollment (during the previous term) will have their grade confirmed after their current class ends for enrollment in the following term.

It is not sufficient to be enrolled in Chem 1A(D)/1AL (or 4A) during the Summer along with Biology 1A/1AL.

AP Biology Exam (or any other similar exam for biology) credit does not provide an exemption from the prerequisites.

Simultaneous Enrollment Requirement:

Students are required to be enrolled in both Bio 1A and Bio 1AL simultaneously. Enrollment in the two courses may be done in any order, but enrollment in both courses is required by the beginning of classes.

Students who have enrolled in Bio 1AL are guaranteed a seat in Bio 1A, but enrollment in Bio 1A does not guarantee enrollment in Bio 1AL. This means that space will be made available in the Bio 1A course for students to enroll if they are already enrolled in Bio 1AL, but it does NOT mean that students will be automatically enrolled in one course if they enroll themselves in 1AL. Students must enroll themselves in both courses separately.

Students who are unable to enroll in both courses (because one course is full) should focus on enrollment in Bio 1AL as it is the more restricted course for enrollment, and enrollment in Bio 1AL will be the determining factor for enrollment in both courses. Students enrolled in Bio 1A but on the waiting list for Bio 1AL may be dropped from Bio 1A to allow students who are enrolled in Bio 1AL to enroll in Bio 1A.

Exemptions from the Requirement:

There are some cases where students may be exempted from the simultaneous enrollment requirement. In all cases, All exemptions from the simultaneous enrollment requirement must be approved by the Biology 1A/1AL Coordinators. 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. A student who has completed both Bio 1A and Bio 1AL previously (received grades), but the student received non-passing grades in one or both courses. In this case, the student may be permitted to repeat the courses (that they did not pass) to attain passing grades. See the Repeating Enrollment section below.

  2. A student has already completed (and passed) a course equivalent to Bio 1A or Bio 1AL at another school. Please use the Completed Equivalent Exemption Request Form to submit a request for an exemption of this type.

  3. The student has ALREADY (at the time of enrollment) declared a major in Chemical Engineering, Mechanical Engineering, or Electrical Engineering & Computer Science. In this case, the student may request to be exempt from the simultaneous enrollmnet requirement to be enrolled only in Bio 1A. Please use the Declared Major Exemption Request Form to submit a request for an exemption of this type.

  4. For any other reason a student may have for requesting an exemption, please use the General Exemption Request Form to submit a request for an exemption from the simultaneous enrollment requirement.

The number of seats that will be permitted for single enrollment (only in Bio 1A or only in Bio 1AL) is limited. A student may be approved for an exemption from the simultaneous enrollment requirement may have to wait to be confirmed for enrollment, or they could be pushed to the waitlist from enrollment if there are not enough single enrollment seats available. Priority will be given in order of submitted requests for exemption.

Discussion and Lab Section Matching Required:

Students are required to enroll in Bio 1A discussion and Bio 1AL Lab sections with corresponding last numbers. Therefore, a student enrolling in Bio 1AL lab sections 215 or 225 must enroll in Bio 1A discussion section 105.

Any student found to have their discussion section not matching with the last number of the last section number they are enrolled will have their discussion section enrollment changed near the beginning of classes.


Enrollment Priority:

Priority for enrollment is on a first-come first-served basis. No speical priority is given based upon major or class level (except as noted for students repeating enrollment (deatiled in the next section) or for any case where a student is approved to enroll only in one course or the other). Higher level students should not have problems enrolling as long as they attempt to enroll at their first possible time. Students repeating enrollment may be given lower priority than students enrolling for the first time (see below).

The wait lists may not be opened until the class enrollment gets close to the enrollment limit.

Repeating Enrollment:

Students are classified as "Repeating Enrollment" if :

1) They have a previous grade in either Bio 1A or 1AL or

2) They were enrolled in Bio 1A/1AL after the Early Drop Deadline in Fall/Spring or the end of the first week of classes in Summer Session and dropped one or both classes. The only exception would be if there were special circumstances which were explained to the Bio 1A/1AL Academic Coordinator or Enrollment Coordinator at the time of the drop.

Students who are repeating enrollment may be given low priority to be enrolled in the courses if the enrollment demand significantly exceeds the maximum capacity. In this case, students repeating who have already passed will always have lowest priority, then students repeating for a 2nd time or more, then those repeating for the first time. This could result in students being dropped from enrollment if they are repeating.

Students who have already received a passing grade (C- or higher or a PASS) should not enroll in the courses and should submit a request for approval to enroll. It will not be possible to approve enrollment to students to repeat the courses if they have already received a passing grade until it is certain other students who have not yet passed the courses have full chance to be enrolled. Approval for enrollment in this case cannot be granted until the first week of instruction.
