UW–Madison BIOLOGY 151: Introductory Biology
BIOLOGY 151 (cross-listed with ZOOLOGY and BOTANY 151) is the first semester of UW–Madison's two-semester majors biology sequence — cellular and molecular biology, genetics, and the start of evolution — with lectures, discussions, and labs in a five-credit package taken by huge premed and bioscience cohorts.

Build my BIOLOGY 151 study planWhat makes it hard
The volume is the challenge: molecular detail, genetics problem-solving, and lab deliverables all running in parallel, with exams that blend recall and application questions memorization alone can't answer. The five-credit format generates deadlines on multiple tracks at once, and falling behind in a cumulative course this dense compounds quickly.
What you'll cover
- • Cell structure and function
- • Energy and metabolism
- • Molecular biology and gene expression
- • Genetics and inheritance
- • Evolution fundamentals
- • Lab skills and experimental design
The BIOLOGY 151 study guide
How to study for UW–Madison BIOLOGY 151, step by step.
- 1
Study processes, not vocabulary lists
Exams blend recall with application: what happens, why, and what changes if a step fails. For metabolism, gene expression, and cell division, learn the mechanism as a story you can interrogate, not a term list.
- 2
Do genetics problems, don't read them
Crosses, pedigrees, and probability questions are problem-solving, and the only preparation is working problems cold. Genetics is where exam scores separate most visibly.
- 3
Self-quiz weekly with application questions
Practice predicting outcomes — a mutation's effect on expression, a cross's offspring ratios — rather than rereading notes. Prediction practice is the closest match to the exam format.
- 4
Keep lab on its own track
The lab carries real weight and steady deadlines. Draft each report soon after the session so lab work never competes with exam weeks for the same nights.
- 5
Review old units in spaced passes
The course is cumulative and later units assume the molecular foundation. A short weekly pass over earlier flashcards keeps the volume manageable instead of terrifying.

FAQ
Is BIOLOGY 151 at UW–Madison hard?
It's demanding through volume and parallel tracks: deep molecular and genetics units, application-heavy exams, and a lab with steady deliverables. Consistent weekly review and genuine genetics problem practice handle it; cramming visibly doesn't.
What's the difference between BIOLOGY 151 and ZOOLOGY 151?
Nothing — the course is cross-listed under BIOLOGY, ZOOLOGY, and BOTANY with identical content. Enroll under whichever listing fits your record; it's the same lectures, labs, and exams.
How do I study for BIOLOGY 151 exams?
Spaced flashcard review for the volume, plus weekly application practice: predict outcomes, explain mechanisms, work genetics problems cold. Exams apply concepts to scenarios, so prediction practice beats rereading by a wide margin.
