Living Environment & Biology Regents Practice & Study Guide
Taking the Regents in 2027? Living Environment had its last exam in June 2026 and has been replaced by the new Life Science: Biology Regents (first given June 2025), but the biology underneath is the same. Both exams lean hard on reading comprehension: many questions hand you a diagram, data table, or passage and ask you to reason from it. That's a skill you build by doing real questions. RegentsLab's Living Environment bank holds hundreds of actual past-exam questions with full explanations, organized by the same units your course follows.
What's on the Living Environment Regents
RegentsLab organizes its Living Environment question bank into the units below — the same structure the exam draws from:
- Cell Biology
- Genetics
- Evolution
- Ecology
- Human Systems
- Scientific Inquiry
Ecology and genetics are the highest-volume units; scientific-inquiry questions (experimental design, controls, variables) appear throughout every part of the exam.
Exam format
The exam runs 3 hours and mixes multiple-choice with constructed-response questions, including a section tied to the state's required laboratory experiences. The new Life Science: Biology Regents (which replaced Living Environment after June 2026) is aligned to the NYSSLS standards and leans more on real-world phenomena, but the content units below are the durable core tested on both.
How to practice
Drill real past-exam questions topic by topic — every question includes a full worked solution. Complete exam simulations for Living Environment are being added; the question bank is live now. Start in the practice lab, and keep the official reference materials open beside you — building fluency with them is part of the preparation.
Frequently asked questions
What score do you need to pass the Living Environment Regents?
A scaled score of 65. One science Regents is required for graduation, and biology (Living Environment, now Life Science: Biology) is the one most students use.
What topics are on the Living Environment Regents?
Cell structure and processes, genetics and biotechnology, evolution, ecology, human body systems and homeostasis, and experimental design — plus questions drawn from the required state labs.
Is the Living Environment Regents multiple choice?
Mostly, but not entirely — expect constructed-response questions where you write short answers, read data tables, and interpret experiments, alongside the multiple-choice sections.
Is the Living Environment Regents being replaced?
Yes. The Living Environment exam had its last administration in June 2026. It is replaced by the new Life Science: Biology Regents, which debuted in June 2025. The core biology content overlaps heavily, so practicing real past questions still pays off.
How should I study for the Living Environment Regents?
Do real past-exam questions by topic, and read the explanation every time you miss — the exam reuses the same concepts and even similar diagrams year after year.
