Campbell Biology
Lisa A. Urry, Michael L. Cain, Steven A. Wasserman, Peter V. Minorsky, Rebecca B. Orr · 12th Edition · ISBN 9780135988046 · Pearson
Complete chapter-by-chapter study guide aligned with Campbell Biology (12th Edition). Includes summaries, learning objectives, and exam-style practice questions for all 56 chapters.
Overview
Campbell Biology (12th Edition) is the gold-standard introductory biology text for majors, and its breadth — from molecules to ecosystems — is what makes it so demanding to study for. This guide matches the 12th Edition chapter for chapter, so you review in the same sequence your course follows and keep lecture, lab, and exam aligned. It distills each unit — the chemistry of life, the cell, genetics, molecular biology, evolution, and ecology — into the core concepts, processes, and vocabulary that exams test, with the key pathways (cellular respiration, photosynthesis, the cell cycle, gene expression) broken down step by step. You get high-yield summaries, must-know terms, and practice questions modeled on how intro bio is tested, so you can spend your time on understanding rather than re-reading dense chapters. Whether you're prepping for a unit exam, a cumulative final, or a foundation for the MCAT, it helps you focus where the points are.
Aligned with introductory biology for majors — the practice questions mirror how core concepts, processes, and vocabulary are tested on course exams, and the foundational topics overlap with MCAT biology.

Questions about this study guide
What exactly do I get?
A printable PDF study guide covering all 56 chapters of Campbell Biology (12th Edition) — chapter summaries, learning objectives, and exam-style practice questions with rationales. One file, lifetime access, no subscription.
How soon will I get it?
Instantly. A download link appears on screen and lands in your inbox the moment your payment clears.
Does this match the 12th Edition?
Yes — it follows the 12th Edition's chapter numbering and units. The 11th and 13th editions map closely, with minor reorganization of a few chapters.
Will it help with hard pathways like respiration and photosynthesis?
Yes — those high-yield processes are broken into clear, step-by-step summaries with exam-style questions, since they're among the most commonly tested topics in intro bio.
Is this useful for the MCAT?
The foundational molecular, cellular, and genetics content overlaps with MCAT biology, so it's a helpful basics review, though the MCAT also requires dedicated prep materials.
Will it match my edition?
This guide is built around the 12th Edition. If your class uses a different edition, chapter numbering may shift slightly, but the topics and learning objectives are usually unchanged.
Do I still need the textbook?
The study guide is a companion, not a replacement — it helps you study efficiently and review fast, but you'll still want the textbook for full depth and any assigned readings. You can buy new, rent, or find a used copy through the price links on this page.
What if it is not what I expected?
Every purchase is backed by a 14-day money-back guarantee — email us within 14 days for a full refund.
Is this a test bank or copied from the textbook?
No. This is an original study guide written to align with Campbell Biology — summaries, objectives, and practice questions with rationales, not a reproduced publisher test bank or copied text.
