You’re sitting in a high school cafeteria or a stuffy classroom. The proctor is walking around with those thick booklets. You open it up, and suddenly, the cell membrane looks like a bunch of random jellybeans and the graph about deer populations makes no sense. This is the Living Environment Regents. It’s a beast. Most people think they can just memorize the parts of a plant and call it a day. Honestly, that’s how you fail. The New York State Education Department (NYSED) loves to hide the actual answer behind a wall of text or a weird diagram you’ve never seen before. If you want to actually pass this thing—or hit that 85 mastery score—you need to stop reading the textbook and start hacking the way the questions are written.
Biology regents practice questions aren't just about "knowing" biology. They're about reading comprehension and logic. You could be a literal brain surgeon, but if you don't know how to interpret a four-line prompt about a specific species of finch on the Galapagos Islands, you’re going to lose points. It’s annoying. I know. But once you see the patterns, it gets a lot easier.
The State's Secret Formula for Living Environment Questions
Most students walk into the test thinking they’ll see a question like "What does the mitochondria do?" That almost never happens anymore. Instead, they’ll give you a paragraph about a marathon runner whose muscles are burning and then ask which organelle is working overtime. It’s the same answer (energy/ATP), but it’s wrapped in a "real-world" scenario. This is what teachers call "application." Basically, the state wants to see if you can use your brain, not just your memory.
Take the 2023 exam, for instance. There was a section about the "Emerald Ash Borer," an invasive beetle. You didn't need to be an expert on beetles. You just needed to understand how invasive species mess up an ecosystem's stability. If you see a question about a "newly introduced organism," 99% of the time, the answer involves a lack of natural predators and a decrease in biodiversity. It’s a script. Once you learn the script, the biology regents practice questions start feeling like a game you’ve already played.
Why the Multiple Choice Section is a Trap
The first 30 questions (Part A) are usually straightforward content. But Part B-1 and B-2 are where the wheels fall off for a lot of kids. These are the questions based on data tables and graphs. NYSED loves a good line graph.
One of the biggest mistakes? Not looking at the units. If the Y-axis says "Rate of Photosynthesis" and the X-axis says "Temperature," and the line goes up and then drops off a cliff, that drop isn't a mistake. It’s the enzymes denaturing. If you just look at the line and say "it went down," you get zero points. You have to explain why it went down. Heat changes the shape of proteins. If the shape changes, the function is gone. Game over for the enzyme.

Cracking the Code of the Living Environment Lab Questions
You’ve got those four state labs: Making Connections, The Beaks of Finches, Relationships and Biodiversity, and Diffusion Through a Membrane. You know them. You probably spent a week in class measuring your pulse or staring at red onion cells under a microscope.
The Regents will ask about these. Usually in Part D.
- The Beaks of Finches: It’s all about competition. If two birds have the same beak, they fight for the same food. One wins, one moves or dies.
- Diffusion Through a Membrane: They always ask about the starch and the indicator. Remember: Starch is too big to move. Glucose is small. If the bag turns blue-black, the iodine (indicator) moved in.
- Making Connections: This is the pulse rate one. It’s about "homeostasis." That’s the magic word. If your heart beats faster, it’s to get more oxygen to the cells and get rid of $CO_{2}$.
- Relationships and Biodiversity: This is where you used paper chromatography to see which plants were related. It’s about evolutionary links. Molecular evidence (DNA) is always stronger than just looking at the plant.
If you’re doing biology regents practice questions and you aren't hitting these lab themes hard, you’re leaving 10 to 15 points on the table. That’s the difference between a 65 and an 80.
The "Must-Know" Vocabulary That Isn't in the Dictionary
There are certain words that show up in almost every single test. If you don't know these, the questions will look like they’re written in another language.
- Homeostasis: Staying the same. Balance. If you're hot, you sweat. That’s homeostasis.
- Metabolism: All the chemical reactions in your body. Every single one.
- Abiotic vs. Biotic: This is middle school stuff, but they still use it to trip you up. Abiotic is dead stuff (rocks, sun, water). Biotic is living (bacteria, squirrels, your annoying cousin).
- Niche: An organism's job. If two animals have the same niche, they're going to scrap.
- Differentiation: This is a big one. All your cells have the same DNA. Your skin cell and your brain cell are identical in terms of their "instruction manual." But they use different parts of that manual. That’s differentiation.
Tackling the Short Answer (Part C) Without Losing Your Mind
Part C is the "Constructed Response" section. This is where students usually give up and start drawing doodles of cats in the margins. Don't do that. Even a "bad" answer can get a point if it hits a keyword.

The biggest tip for Part C? Don't over-explain. If the question asks for "one reason," give them one reason. If you give two and the first one is right but the second one is wrong, they will mark the whole thing wrong. Seriously. It’s called "negation." Just give them exactly what they asked for and then stop writing.
Often, these questions ask you to design an experiment. You’ll need a "control group" (the group you do nothing to) and an "experimental group." You’ll need a "large sample size" to make the results "more valid." You’ll need one "independent variable" (the thing you change). If you memorize that template, you can answer almost any experimental design question they throw at you, whether it’s about plant fertilizer or a new headache pill.
The Evolution and Genetics Heavy Hitters
Evolution is a massive part of the Regents. Charles Darwin is the star of the show. But remember: individuals don't evolve. Populations do. A giraffe didn't stretch its neck and then have a long-necked baby. That’s Lamarck, and he was wrong. Instead, the short-necked giraffes died because they couldn't reach the leaves, and the long-necked ones survived to have babies. Natural selection.
In genetics, it’s all about protein synthesis. DNA $\rightarrow$ RNA $\rightarrow$ Protein $\rightarrow$ Trait. If you change the DNA (a mutation), you change the protein. If you change the protein, the trait changes. It might be a good change, but it’s usually bad. Think of it like a typo in a recipe. If the recipe calls for salt and you put in sugar, the cake is going to taste weird.
How to Actually Study Using Biology Regents Practice Questions
Don't just take a practice test and check your score. That's a waste of time. You need to do "active review."

Open up the nysedregents.org archive. It’s free. It has every test going back twenty years. Pick a test, say June 2022. Do Part A. Then, look at the answer key. For every question you got wrong, don't just look at the right letter. Find out why the other three were wrong.
Let's say the question was about carrying capacity. You picked "unlimited growth." The right answer was "limited resources." Why was your answer wrong? Because in the real world, nothing grows forever. There’s only so much pizza at the party. Once the pizza is gone, the party stops growing. That’s carrying capacity.
Managing the Clock on Test Day
You have three hours. That is an insane amount of time for this test. Most people finish in ninety minutes. Use that extra time to go back and read the questions again. Literally. Read them out loud in your head.
Wait for the "except" or "not."
"Which of these is NOT a function of the cell membrane?"
If you skip that "NOT," you're going to pick the first right thing you see and lose a point.
Actionable Steps for Your Final Prep
Stop highlighting your whole textbook. It doesn't work. Instead, do this:
- Download the last three years of exams. June and August are the big ones. January tests are usually a bit weirder, but still good practice.
- Master the "Identify, State, Explain" format. If a question says "Identify," just name it. If it says "Explain," you need a "because" in your sentence.
- Focus on Ecology and Human Impact. This section is usually the largest chunk of the test. Global warming, deforestation, and fossil fuels are guaranteed to be there. Remember: "Trade-offs." We use cars because they’re fast (benefit), but they pollute (cost). The Regents loves the word "trade-off."
- Practice the Graph. Get some graph paper. Practice plotting points and drawing a line of best fit or connecting the dots (the Regents usually tells you to "surround each point with a circle"). If you don't circle the points, you lose the point. It’s a dumb rule, but it’s the rule.
- Check the Glossary. If you don't know what "pathogen," "antibody," or "antigen" means, look them up right now. They show up in the immune system questions every single time. An antibody is a weapon; an antigen is the "ID tag" on the germ.
Get a good night's sleep before the test. No, seriously. Your brain needs to prune its synapses and consolidate your memories. If you pull an all-nighter, you’ll forget the difference between mitosis and meiosis. (Mitosis is "my-toes," it happens in your body cells. Meiosis is "me-oh-my," it makes babies). You've got this. Just stay calm, read the prompts carefully, and remember that the answer is almost always hidden somewhere in the text they gave you.
Your High-Value Checklist
- Review the State Labs (Specifically the "Beaks of Finches" and "Diffusion" scenarios).
- Practice 50 Multiple Choice Questions from the most recent June exam.
- Draw a Food Web and practice predicting what happens if one organism is removed.
- Memorize the Protein Synthesis Pathway (DNA to RNA to Protein).
- Identify Three Human Impacts on the environment and a specific "trade-off" for each.
By focusing on the logic of the questions rather than just raw facts, you'll find the exam much more manageable. The state isn't trying to trick you into failing; they're trying to see if you can think like a scientist.
