Texas A&M BIOL 112: Introductory Biology II
BIOL 112 is the second course in Texas A&M's majors biology sequence, covering evolution, ecology, organismal diversity, and plant and animal physiology, with an integrated lab. It completes the foundation BIOL 111 started for biology majors and the large pre-health pipeline.

What makes it hard
The breadth flips: where 111 drilled deep into molecular detail, 112 sweeps across the entire tree of life and ecosystem-level thinking, so the challenge becomes organizing volume rather than memorizing depth. Exams reward comparative frameworks (how lineages differ, how systems solve the same problem), and students who study each chapter as an island drown in unconnected facts.
What you'll cover
- • Evolution and natural selection
- • Phylogenetics and the diversity of life
- • Ecology and ecosystems
- • Plant structure and physiology
- • Animal physiology
- • Population and community dynamics
The BIOL 112 study guide
How to study for Texas A&M BIOL 112, step by step.
- 1
Study comparatively, not chapter by chapter
BIOL 112's exams reward frameworks: how lineages differ, how systems solve the same problem. Build comparison tables across organisms instead of memorizing each chapter as an island.
- 2
Make evolution the organizing thread
Every unit connects through evolutionary logic. Asking why a trait exists turns disconnected facts into a structure that holds under exam pressure.
- 3
Draw the cycles and systems from memory
Redraw nutrient cycles, physiological feedback loops, and life cycles cold, then check the gaps. Retrieval beats rereading at this volume.
- 4
Keep flashcards running daily
The vocabulary load across taxonomy and physiology is heavy, and short daily passes hold what weekend sessions lose.

FAQ
Is BIOL 112 harder than BIOL 111?
Different. 111 is depth (molecular detail); 112 is breadth (the whole tree of life plus ecology and physiology). Students who build comparative frameworks find 112 more manageable; students who memorize chapter by chapter find the volume overwhelming.
Do pre-med students need BIOL 112 at Texas A&M?
Yes. It completes the introductory biology foundation pre-health tracks require, and its evolution, physiology, and ecology content appears on the MCAT. Genuine mastery here pays off again at test time.
How should I study for BIOL 112 exams?
Build comparison tables across organisms and systems, redraw cycles from memory, and run daily flashcards for the vocabulary load. The exams reward connected understanding, with evolution as the through-line, over isolated facts.
