Cornell Biology Major (Course Requirements)
Cornell’s Biological Sciences major is offered through college-specific degree paths, so there is no single checklist that fits every student. Your required biology, supporting-science, laboratory, elective, and college courses depend on your admitting college and catalog year. Confirm those rules in Cornell’s current catalog and degree audit before planning courses or relying on transfer credit.
Choosing a biology major can feel like sorting through two maps that use many of the same words but lead to different degree requirements. At Cornell, the key is to identify the college that will award your degree, then follow that college’s rules alongside the Biological Sciences major checklist.
I often advise students to start with the requirements, not with a course list shared by a friend. A course may count toward the major for one student and not another, even when both study biology. The practical goal is to know which rules apply to you, how courses fit together, and whom to ask before making decisions that affect your time or cost.
Cornell Biological Sciences: College Options, Admissions, and Program Overview
Cornell’s Biological Sciences major is tied to the college in which you enroll. Students commonly consider paths through the College of Agriculture and Life Sciences (CALS) and the College of Arts and Sciences (A&S). Their degree and college requirements can differ, so check the current catalog for your intended college and entry year.
The major gives students a structured way to study living systems, while college requirements provide a broader academic framework. Cornell’s institutional accreditation by the Middle States Commission on Higher Education applies to the university; it does not make the two colleges’ degree checklists interchangeable.
How the college choice affects your degree
Your college determines the type of bachelor’s degree awarded and the college-wide requirements you must meet. CALS and A&S have distinct curricula and degree rules. The major name alone does not tell you whether a course meets a college distribution, residency, or other degree requirement.
| Planning question | What to check | Why it matters |
|---|---|---|
| Which college will admit me? | The current Cornell admissions and college pages | Your college sets part of your degree plan |
| Which biology checklist applies? | The major requirements for your college and catalog year | Major rules may differ by college or year |
| What degree will I earn? | The college’s current degree information | BA and BS pathways can have different college rules |
| Will an outside course count? | Written review from the relevant Cornell office | Transfer credit may not satisfy a specific major requirement |
When comparing pathways, look beyond the letters BA or BS. Compare the actual course, distribution, and residency rules, along with the academic setting that best fits your interests. Ask the college or major advising office to explain any requirement that is unclear before you commit to a plan.
Admissions and preparation
Cornell does not publish a universal GPA or SAT/ACT score that guarantees admission. Admissions decisions consider an application as a whole, and testing policies, deadlines, and application details can change. Use Cornell’s current admissions information rather than an old checklist or a single score shared online.
For high school students, a strong foundation in biology, chemistry, mathematics, and physics can help prepare you for college science. Transfer applicants should keep course syllabi and detailed descriptions. These materials can help Cornell evaluate what a prior course covered, but they do not guarantee that it will meet a specific Cornell requirement.
Degree Curriculum: Biology Core, Supporting Sciences, Laboratories, and College Requirements
The curriculum combines biology courses with supporting sciences, laboratory learning, electives, and college-wide requirements. The exact course names and number of credits depend on your college and catalog year. Use the official checklist for your program to confirm every required category instead of relying on a general biology plan.
What to map in the major checklist
A major checklist is an official record of the courses and other rules students must complete for a program. For Biological Sciences, review the current college-specific list for biology requirements, supporting science courses, lab expectations, electives, and any rules about course level or grades.
Do not assume that a course counts because its title includes “biology” or because it transfers as college credit. Credit transfer and requirement approval are different decisions. A course might earn credit but still not satisfy a named major, laboratory, or college requirement.
Major requirements versus degree requirements
Major requirements cover the field of study. College requirements can include broader distribution, language, writing, residency, or other rules. Cornell bachelor’s degrees generally require at least 120 credits, but reaching 120 credits alone does not mean you have met every rule needed to graduate.
| Requirement area | What to verify | Planning action |
|---|---|---|
| Biology | Required courses and approved electives | Follow the checklist for your college and catalog year |
| Supporting sciences | Which science and math courses are required | Check prerequisites and course sequences early |
| Laboratory work | Which courses include required lab components | Confirm the lab course itself is approved |
| College requirements | Distribution, writing, language, or other rules | Track these outside the major checklist |
| Total credits and residency | Minimum credits and where they must be earned | Review your college audit with an adviser |
A course can serve more than one purpose only if Cornell’s rules allow it to do so. Ask an adviser whether any overlap is permitted; do not count the same course twice on your own. A term-by-term degree audit can reveal gaps before they become difficult to fix.
Build a course sequence before registration
Some science courses may rely on earlier coursework, and lab sections can affect schedule choices. Start by marking prerequisites and courses offered in a particular term, using Cornell’s current course information. Then compare that sequence with your college and major requirements.
A useful planning routine is:
- Confirm your catalog year and the correct major checklist.
- Mark completed courses, current courses, prerequisites, and remaining requirements.
- Check course availability and registration details in Cornell’s current systems.
- Review the plan with an academic adviser before registration.
- Recheck the degree audit each term, especially after changing majors or receiving transfer credit.
Academic Success and Student Experience: Advising, Research, and Course Planning
Advising helps students interpret rules and make a course plan that fits their academic progress. Research, internships, and other learning experiences can help you explore biology, but they do not automatically replace required courses. Keep your academic plan and your career exploration connected without confusing one for the other.
Use advisers to resolve requirement questions
At enrollment, ask which catalog year governs your degree and where to find the official checklist. Your college registrar or major advising office can help explain requirements and review questions about substitutions, transfer courses, or degree audits. Save written approvals and note who issued them.
This step matters most when a course is unusual, taken elsewhere, or being used for more than one requirement. Before enrolling in an outside course, request a decision from the relevant Cornell office. Getting approval in writing can reduce the risk of paying for a course that does not meet the requirement you had in mind.
Research and other learning experiences
Research can help you test your interests and learn how scientific questions are studied. Internships, clinical exposure, and other experiences can also help you explore possible directions. These activities may be valuable, but check whether they carry credit and whether that credit fits your degree plan before treating them as part of graduation requirements.
I recommend that students explore opportunities while keeping their required coursework visible. For example, a student interested in health professions should check those programs’ prerequisites separately. Completing the biology major does not, by itself, confirm that every graduate or professional program prerequisite has been met.
Planning scenarios: how the rules apply
These examples are hypothetical planning situations, not reports about individual Cornell students. They show why a student should use the correct college checklist and ask for course decisions before relying on them.
- A first-year student choosing a college: Compare the current CALS and A&S degree rules, then review the Biological Sciences checklist for the college you plan to enter. Do not choose based only on a course list from another student.
- A transfer student with prior lab courses: Gather syllabi and course descriptions, then ask Cornell to evaluate each course. A transfer-credit award does not automatically mean the course fulfills a specific biology or lab requirement.
- A student considering a career in health: Map Cornell degree requirements and the separate prerequisites for possible professional programs. Check requirements with each program because they may not match the biology major checklist.
Career Pathways and Employment Outcomes: Research, Health Professions, and Graduate Study
Biological Sciences can support further study and a range of work related to life science, but the major does not guarantee a particular job or admission to a later program. Your opportunities depend on your courses, experience, interests, and the requirements of employers or graduate and professional programs.
As you progress, use advanced courses, research, internships, or clinical exposure to test possible interests. If graduate or professional study is a goal, make a separate list of prerequisites and deadlines. Compare that list with your Cornell audit each year so you can address gaps while you still have room to plan.
Frequently Asked Questions
These answers provide general guidance, not a substitute for the catalog or an official degree audit. Cornell requirements can vary by college and entry year. Use the current checklist for your program and ask the relevant advising office to confirm any decision that affects a major, transfer, or graduation requirement.
Is Cornell’s Biological Sciences major the same in CALS and A&S?
The major is not governed by one universal checklist. CALS and A&S have different college degree rules, and the applicable major requirements can depend on your college and catalog year. Check the current catalog and degree audit for the college that will award your degree.
What courses are required for Cornell Biological Sciences?
The program includes biology, supporting sciences, laboratory learning, and electives, but the exact courses depend on your college and catalog year. Consult the current official checklist rather than using an online list that may apply to another student or an older curriculum.
Does Cornell require 120 credits to graduate?
Cornell bachelor’s degrees generally require at least 120 credits. That minimum does not replace major, college, residency, or other degree requirements. Check your college’s rules and degree audit to confirm that you have completed every requirement.
Is the BA or BS better for biology?
Neither degree label alone tells you which path is best. Compare the current college requirements, curriculum, and degree structure, then consider your academic goals. The college that admits you sets the rules you must follow for your degree.
Can transfer courses fulfill major requirements?
Possibly, but Cornell and the relevant college must evaluate them. A course may transfer for credit without satisfying a particular biology, lab, or college requirement. Get an official decision before relying on outside coursework in your plan.
Is there a minimum GPA or test score for admission?
Cornell does not publish a universal GPA or SAT/ACT score that guarantees admission. Admissions policies and application details can change. Check Cornell’s current admissions information for the requirements and deadlines that apply to your application cycle.
Does the biology major meet health-profession prerequisites?
Not necessarily. Health-profession programs set their own prerequisites, which may differ from Cornell’s major requirements. Identify the programs you may apply to and confirm their current requirements directly, then compare them with your degree plan.
Who can confirm which checklist applies to me?
Your college registrar or Biological Sciences major advising office can help confirm the applicable rules. Ask which catalog year governs your degree and request written guidance when a course, transfer credit, or substitution may affect a requirement.
What should transfer applicants keep from previous courses?
Keep syllabi, course descriptions, and other detailed records that show course content and lab work. Cornell may use them to assess transfer coursework. Retaining these materials can help the relevant office review whether a course fits your intended plan.
How often should I review my degree progress?
Review your degree audit and major checklist at least each term, and before registration or a major change. This gives you time to check prerequisites, course availability, and any requirement that remains incomplete.
