UC Davis BIS 102 Before 101 (Prerequisite Rules)
At UC Davis, BIS 101 is listed as a prerequisite for BIS 102, so students should plan to complete BIS 101 first. Do not assume you can take both courses at once. Before registering, check the current General Catalog and the Schedule Builder listing for your intended term. If you have equivalent coursework or a registration error, ask the department or an advisor about official prerequisite review.
A course sequence can look flexible on a degree plan, but registration rules still matter. If BIS 102 appears in your plan before BIS 101, that does not by itself mean you are eligible to enroll. The key question is whether UC Davis recognizes the prerequisite as completed, or has approved another basis for enrollment.
I recommend checking both the catalog and Schedule Builder before making plans around a particular quarter. The catalog explains the course’s stated prerequisite; Schedule Builder shows the restrictions and registration instructions for the term you want. If those details affect your graduation plan, bring them to your major advisor early.
BIS 102 prerequisite: the direct answer
A prerequisite is a course or other requirement that a student must meet before enrolling in another course. For BIS 102, UC Davis lists BIS 101 as a prerequisite. Unless the current official listing says otherwise, plan to complete BIS 101 first rather than assume concurrent enrollment is allowed.
In practical terms, students who have not completed BIS 101 may encounter a registration block or other enrollment problem. A student may still ask whether prior coursework can count, but an exception or equivalency review must be approved through the proper UC Davis process. It is not automatic.
The safest answer is therefore: complete BIS 101 before BIS 102, unless UC Davis confirms that you meet the prerequisite another way. Check the exact wording for your term because course listings and registration instructions can change.
What “prerequisite” means for your registration
A prerequisite is an eligibility rule, not just a suggested order for learning the material. It tells students what they must satisfy before taking a course. If the system does not recognize that you have met the rule, you may be unable to enroll even if you believe you are prepared.
For this question, distinguish three things:
- Course order: The recommended or required sequence in your academic plan.
- Prerequisite: The requirement attached to BIS 102 in the official listing.
- Prerequisite clearance: Official recognition that you meet the requirement, including through an approved review when applicable.
A note from an instructor or an informal conversation may be useful guidance, but it may not update the registration system or satisfy the university’s process. Ask what formal action is needed.
Can you take BIS 101 and BIS 102 in the same term?
Concurrent enrollment means taking two courses during the same term. Do not assume that BIS 101 is a co-requisite for BIS 102. A co-requisite is a course that may be taken at the same time as another course, but BIS 101 should be treated as a prerequisite unless the current BIS 102 listing explicitly allows concurrent enrollment.
The distinction matters. If a course has a prerequisite, taking that earlier course at the same time may not meet the rule. If the listing allows a co-requisite or concurrent enrollment, it should say so. Check the wording in the official listing instead of relying on an old syllabus, a classmate’s experience, or an answer from a different term.
| Your situation | What to check | Sensible next step |
|---|---|---|
| You have not taken BIS 101 | BIS 102’s catalog and term listing | Plan to complete BIS 101 first |
| You are taking BIS 101 now | Whether the current listing permits concurrent enrollment | Ask the department or an advisor; do not assume |
| You completed a similar course elsewhere | Whether UC Davis accepts it as equivalent | Request an official review and provide course details |
| You completed BIS 101, but registration blocks you | Whether completion is recorded and what the error says | Contact the relevant department or advising office promptly |
| You are planning a later quarter | The listing for that intended term | Recheck before registration opens |
The table is a planning guide, not an approval. Only UC Davis can determine whether a specific student meets the requirement.
How to check the official BIS 102 rules
The General Catalog and Schedule Builder serve different purposes. The catalog provides the course information and stated prerequisite. Schedule Builder gives term-specific registration details and restrictions. Check both, because the information relevant to your enrollment may depend on the term.
Step 1: Read the General Catalog entry
Open the UC Davis General Catalog and find BIS 102. Read the entire course entry, especially the prerequisite wording. Note whether it identifies BIS 101, equivalent preparation, or any other condition.
Do not rely on a search result snippet alone. It may leave out part of the listing or show information that is not specific to the term you plan to attend.
Step 2: Check Schedule Builder for your term
Open Schedule Builder for the term you want and review the BIS 102 course entry. Check its enrollment restrictions and any instructions about prerequisite checking. Save or note the exact wording, especially if it differs from what you expected.
A course may have different sections or restrictions. Confirm the details for the specific term and section you are considering. If the page is unclear, ask the department or an advisor to explain the rule before you build your schedule around an assumption.
Step 3: Compare the rule with your record
Ask yourself whether you have completed BIS 101 and whether your completion appears in your UC Davis record. If you took a course elsewhere, do not assume that a similar name or subject makes it equivalent. Gather the information UC Davis may need to review it, such as a transcript and course description.
Step 4: Resolve a block before deadlines
If Schedule Builder blocks enrollment, read the message and contact the appropriate department or advising office. Include the term, course, section if relevant, the registration message, and any records that support your request.
Do not wait until the last minute if BIS 102 is important to your plan. A review may take time, and an inquiry does not guarantee approval or reserve a seat.
If BIS 101 is in progress or you took an equivalent course
An in-progress course is a course you are taking now but have not yet completed. If BIS 101 is in progress, ask whether the current term’s BIS 102 listing allows enrollment before BIS 101 is complete. Unless the official listing explicitly permits this, do not treat an in-progress course as satisfying the prerequisite.
If you took a comparable course at another college, request an official equivalency review. UC Davis must determine whether that coursework meets the requirement; matching course titles or topics is not enough to establish approval. Keep a transcript and useful course information ready, and ask the department or advising office what documents it needs.
If you already completed BIS 101 but the registration system does not recognize it, report that problem. The issue could involve how your record is displayed or checked, but you should not assume the system will correct itself. Ask which office can review the record and whether any formal clearance is required.
Registration scenarios and next actions
These examples are common planning situations, not guarantees about how UC Davis will decide an individual case.
| Scenario | What it does not prove | Next action |
|---|---|---|
| “I am enrolled in BIS 101 this term.” | It does not prove BIS 102 allows concurrent enrollment. | Check the current listing and ask for guidance. |
| “My other college course covered similar material.” | Similar content does not establish UC Davis equivalency. | Request an official review with supporting records. |
| “An instructor said I seem ready.” | Informal approval may not satisfy registration rules. | Ask whether formal prerequisite clearance is needed. |
| “The system says I do not meet the prerequisite.” | The message alone may not explain the reason. | Share it with the department or advising office and ask how to resolve it. |
| “My degree plan shows BIS 102 next.” | A plan does not replace the course’s enrollment restriction. | Confirm eligibility and adjust the plan if needed. |
Plan the BIS 101–BIS 102 sequence with an advisor
Course sequencing is the order in which courses are taken to meet degree requirements. If BIS 101 must come first, a delay in completing it may affect when you can take BIS 102 and any later course that depends on it. The effect on your own degree plan depends on your major requirements and course schedule.
If the sequence could affect graduation timing, meet with your major advisor before changing your plan. Bring your current academic plan, the catalog entry, the Schedule Builder information, and any relevant transfer-course records. Ask which future courses depend on BIS 102 and what alternative schedule, if any, fits your degree requirements.
Trying to enroll without recognized prerequisite completion or approved clearance can lead to a registration block or removal from a course. That may disrupt later coursework. It is better to resolve the question before registration deadlines than to assume an exception will be granted.
Next step: Verify the rule, confirm how UC Davis records your preparation, and then build your course plan around the answer you receive.
Frequently asked questions
Can I take BIS 102 before BIS 101 at UC Davis?
BIS 101 is listed as a prerequisite for BIS 102. Plan to complete BIS 101 first unless UC Davis confirms that you meet the requirement another way.
Can I take BIS 101 and BIS 102 at the same time?
Do not assume so. Concurrent enrollment is allowed only if the current BIS 102 listing explicitly permits it.
Is BIS 101 a co-requisite for BIS 102?
Treat BIS 101 as a prerequisite, not a co-requisite, unless the current official listing states that concurrent enrollment is permitted.
What if I am taking BIS 101 right now?
Check the term-specific Schedule Builder entry and ask the department or an advisor whether you may enroll in BIS 102. Being enrolled in BIS 101 does not automatically satisfy a prerequisite that must be completed first.
What if I took an equivalent course at another college?
Ask UC Davis for an official equivalency or prerequisite review. Provide the records requested, such as a transcript or course information. Do not assume that a similar course title is enough.
What if I completed BIS 101 but Schedule Builder blocks me?
Check your record and the registration message, then contact the relevant department or advising office. Ask what documentation or clearance is needed.
Will an instructor’s approval let me enroll?
Not necessarily. Informal approval may not satisfy the university’s registration process. Confirm whether official prerequisite clearance is required.
Where should I verify the prerequisite?
Check the BIS 102 entry in the UC Davis General Catalog and the Schedule Builder listing for your intended term. Use both sources before registering.
Could a BIS 102 prerequisite issue delay my degree plan?
It could affect later coursework if BIS 102 is needed for courses you plan to take. Ask your major advisor to review the sequence and help you adjust your plan.
Does an exception happen automatically?
No. If you believe prior coursework or another circumstance meets the requirement, ask the department or advising office whether an authorized review is available. Clearance is not automatic.
