Cornell Biology Courses (Curriculum Selection)
Cornell undergraduates can study Biological Sciences through either the College of Agriculture and Life Sciences (CALS) or the College of Arts and Sciences (A&S). The major’s science foundation is shared, but each college has its own degree rules. Start with your college’s current checklist, then map prerequisites, labs, advanced courses, and goals before enrolling.
Choosing biology courses can feel like solving two plans at once: the major and the college degree. The key is to check how each course counts in both places. A class may fit the major but not meet a college distribution or residency rule.
I help students make this process manageable by starting with official requirements, not a long list of interesting course titles. The right plan also leaves room for research, fieldwork, or preparation for a future profession. Requirements can change, so confirm details with Cornell’s current materials and an academic advisor.
Cornell Biology Programs and Admissions Overview
Cornell offers the Biological Sciences major in CALS and A&S. Both paths lead to a bachelor’s degree, but they sit within different colleges and have separate degree requirements. Your first step is to identify the college that fits your interests, then use its current rules to guide course selection.
Choosing between CALS and A&S
CALS and A&S are not interchangeable for degree planning. Each college sets its own requirements for areas such as total credits, distribution, and residency. The same biology course may apply to the major in either college, while applying differently to the college degree.
Compare official college materials before choosing a path or counting a course toward graduation. If you are considering a change of college, ask an advisor how your completed courses would apply under the new rules. Do not assume that an existing degree audit will transfer unchanged.
| Planning question | CALS | A&S |
|---|---|---|
| Is Biological Sciences offered? | Yes | Yes |
| Are college degree rules the same? | No | No |
| What should you check? | Current CALS degree rules and major checklist | Current A&S degree rules and major checklist |
| Who can confirm how a course applies? | Your advisor and official degree audit | Your advisor and official degree audit |
Cornell’s institutional accreditation is through the Middle States Commission on Higher Education. Students can confirm current status through the commission’s directory. For day-to-day planning, the more immediate task is to follow the degree and major rules that apply to your own college and entry year.
Admissions and preparation
Cornell does not publish one GPA that guarantees admission. Students should review the application requirements for their intended college and entry year. Strong preparation in biology, chemistry, mathematics, and lab sciences can help students approach college-level work, but no single course or grade assures admission.
If you are still in high school, focus on the courses available to you and follow Cornell’s current admissions guidance. If you are a transfer applicant, check the requirements and transfer-credit process for the specific college and program. Do not use a major course list as a substitute for admissions instructions.
Biological Sciences Curriculum, Prerequisites, and Degree Requirements
The curriculum combines foundational science with advanced study in biology. Your exact route depends on the current major checklist, college rules, and course availability. Before registration, compare all three and check each course’s prerequisites, co-requisites, class-standing limits, and enrollment controls in Cornell’s Class Roster.
Build the required foundation first
Start with the introductory biology sequence and any required lab or research components listed on the current checklist. Then map supporting subjects, such as chemistry, mathematics, or statistics, in the order required by their prerequisites. A prerequisite is a course or other condition you must meet before enrolling; a co-requisite must be taken at the same time or as specified.
Do not rely on a course title alone. Check its current roster entry for enrollment rules and timing, then confirm that it satisfies the requirement you intend to meet. Sections may differ in meeting times or enrollment controls, so review the details for the specific term.
A simple planning grid can reveal bottlenecks:
| Course area | What to verify | Why it matters |
|---|---|---|
| Introductory biology | Sequence, labs, and listed prerequisites | Establishes the required foundation |
| Supporting sciences | Course order and co-requisites | One course may unlock later options |
| Mathematics or statistics | Major and college applicability | Supports quantitative work and degree progress |
| Advanced biology | Eligibility and topic fit | Builds depth after introductory study |
| Research or fieldwork | Approval, credit rules, and availability | May support learning but may not replace a requirement |
Check every course against both sets of rules
Keep two checklists: one for the Biological Sciences major and one for your college degree. For every planned course, record the course name, term, prerequisite status, and how the official audit applies it. This small habit helps prevent a common mistake: counting a course toward the major without checking whether it also meets a college rule.
If the audit does not show the result you expect, ask an advisor before relying on the course for graduation planning. Course substitutions and transfer credits need official review. Save the advisor’s guidance and check the audit again after the decision is recorded.
A practical sequence is:
- Download the current major checklist for your college.
- Review college degree and residency rules.
- Check prerequisites and enrollment details in the Class Roster.
- Place required courses in a term-by-term plan.
- Review the plan and audit with an advisor each term.
Academic Planning, Research, and Student Experience
A strong course plan meets requirements while building toward an area of interest. Students may be drawn to research, ecology, health fields, biotechnology, or another direction. Use advanced courses to explore that interest, but keep required courses and prerequisites at the center of the schedule.
Choose advanced courses with a purpose
Once you have mapped the foundation, compare advanced biology courses by topic, prerequisites, and fit with your goals. A course that sounds appealing may require preparation you have not completed yet. Check the roster and current major checklist rather than relying on old student notes or third-party lists.
You do not need to settle on a career before choosing an advanced course. Instead, use a few guiding questions:
- Which biological questions do I want to understand better?
- Does this course build knowledge or skills I may use later?
- Have I met its prerequisites?
- Will it fit alongside my other required courses?
- How will it count in my major and college audit?
Research, fieldwork, and internships can add experience, but availability and credit rules vary. Ask the relevant program or advisor how an opportunity works and whether it can count toward a requirement. Treat these experiences as additions to a sound academic plan, not automatic substitutes for required courses.
Planning examples: two common situations
These examples show how to apply the process; they are not records of individual Cornell students. A student interested in ecology might first complete the required biology and supporting science foundation, then explore advanced courses with an ecology focus. The student would check prerequisites and confirm each course’s degree-audit role before registration.
A student interested in health professions might map the biology major alongside the separate prerequisites required by the intended professional programs. Those prerequisites can differ by program, so the student should verify them with each program and an advisor. The major alone does not guarantee completion of every professional-school prerequisite.
For transfer students, the same checks matter even more. Ask Cornell to evaluate prior courses through its official transfer-credit process, then review how approved credit appears in the major and college audit. A course that seems similar by title may not receive the same requirement credit.
The next step in each scenario is the same: update the term plan, check the audit, and discuss any uncertainty with an advisor before registration.
Career Pathways, Graduate Preparation, and Employment Outcomes
Biological Sciences can support several next steps, but course choices should follow the requirements of the path you intend to pursue. Graduate and professional programs set their own entry rules. Employers also value skills and experience that students can explain and show, not only course titles.
Connect coursework to the next step
For graduate or professional study, identify likely programs early enough to review their current prerequisite lists. Compare those lists with the Cornell major and college requirements. If a required subject is missing from your plan, discuss options with an advisor before your schedule becomes difficult to change.
For employment, build and document skills through coursework, research, field projects, internships, or other relevant work. Depending on your experience, that may include lab methods, data analysis, field observation, scientific writing, or teamwork. Do not claim a skill from a course title alone; be ready to describe what you did and what you learned.
At least once each term, review your plan for three things: requirements completed, prerequisites still needed, and experiences that support your next step. This keeps career planning connected to the curriculum without letting it displace degree rules.
Frequently Asked Questions
These answers address common course-planning questions for Cornell Biological Sciences students. Requirements, offerings, and enrollment rules can change, so use the current college checklist, major materials, Class Roster, and degree audit for decisions about a specific term.
Can I major in Biological Sciences in CALS or A&S?
Yes. Cornell offers the Biological Sciences major through both CALS and A&S. The colleges have different degree requirements, so choose the applicable college checklist and audit. Confirm how each course counts for both the major and your college degree.
Are the CALS and A&S biology requirements identical?
Do not assume they are identical. The major has its own checklist, while each college also sets degree rules. Check the current requirements for your college and ask an advisor how a course applies if the audit is unclear.
Where can I check course prerequisites?
Use Cornell’s current Class Roster for the term you plan to take the course. Review prerequisites, co-requisites, class-standing limits, and enrollment controls for the specific course and section before you add it to your plan.
How do I know which biology courses I need?
Use the current Biological Sciences major checklist for your college. It identifies the required foundation and other major components. Compare it with your degree audit and college requirements, then ask an advisor about unclear items or possible substitutions.
Can a biology course count for the major but not my degree?
Yes, a course may satisfy a major requirement without meeting a college distribution, residency, or other degree rule. Check the official audit before relying on it for graduation. Ask an advisor to clarify any mismatch.
Should I choose advanced courses based on career goals?
Career goals can help you choose areas of depth, but first check prerequisites and degree requirements. For graduate or professional study, verify prerequisites with each program. For employment, look for courses and experiences that help you build and demonstrate relevant skills.
How should transfer students plan biology courses?
First, follow Cornell’s official transfer-credit review process. Then check how approved credits apply to the major and the student’s college degree audit. Do not assume that a similar course title will meet a Cornell requirement.
Is there a GPA that guarantees admission to Cornell Biological Sciences?
Cornell does not publish a universal GPA cutoff that guarantees admission. Review current application requirements for the intended college and entry year. Academic preparation matters, but a particular GPA or course list cannot assure admission.
The most reliable plan is the one you verify as you go: use the checklist for your college, check the Class Roster before registration, and review your audit with an advisor each term. That process helps you choose biology courses with purpose while keeping major and degree requirements in view.
