You're sitting at the kitchen table with a high school course catalog, a pencil, and a growing sense of dread. Practically speaking, science. Also, regents. Consider this: credits. Diploma types. It all blurs together after a while.
Here's the short version: most students in New York need one science Regents exam to graduate with a standard Regents diploma. But if you're aiming for the Advanced Regents diploma — or if your school has its own ideas — the number changes.
Let's untangle it.
What Is a Science Regents Exam
New York State doesn't just hand out diplomas based on seat time. You have to prove you learned something. That's where Regents exams come in — standardized, state-administered tests in core subjects.
For science, there are four main options:
Living Environment
This is biology. Cells, genetics, evolution, ecology, human body systems. It's the most commonly taken science Regents, partly because it's often the first science course freshmen or sophomores encounter.
Earth Science
Rocks, weather, astronomy, plate tectonics, the water cycle. There's a lab practical component — you actually have to identify minerals, read topographic maps, and use a sling psychrometer. Yes, that's a real thing.
Chemistry
Atomic structure, bonding, stoichiometry, kinetics, equilibrium, redox, organic basics. Math-heavy. Concept-heavy. The exam includes a reference table you'll either love or memorize by accident.
Physics
Mechanics, energy, electricity, magnetism, waves, modern physics. The most math-intensive of the four. Also has a reference table. Also has a reputation — deserved or not — for being the "hard" one.
There used to be a "Physical Setting/General Science" exam. It's gone. Don't look for it.
Why It Matters / Why People Care
The exam you take — and how many you take — determines more than just a checkmark on a transcript.
Diploma Type Changes Everything
A Regents diploma requires one science Regents exam passed with a 65 or higher. That's it. One.
An Advanced Regents diploma requires two science Regents exams — one from the life sciences (Living Environment) and one from the physical sciences (Earth Science, Chemistry, or Physics). Both at 65+.
That second exam is the gatekeeper. So for some colleges, that matters. Miss it, and you're not getting the "Advanced" designation. For scholarships, it can matter more.
College Admissions Look at the Transcript, Not Just the Diploma
Even if you only need* one for the diploma, competitive colleges expect to see three or four years of lab science. They'll notice if you stopped after Living Environment. They'll also notice if you took Chemistry and Physics but skipped Earth Science — that's fine. They care about rigor, not checkboxes.
Some Schools Add Their Own Requirements
This is the part nobody tells you at orientation. Your district* or school* can require more than the state minimum. I've seen schools mandate two science Regents for all students. Others require a specific sequence: Living Environment → Earth Science → Chemistry. Check your student handbook. Ask your counselor. Don't assume.
How It Works (or How to Do It)
Step 1: Know Your Diploma Track
Are you on track for a Regents diploma or an Advanced Regents diploma? If you're not sure, you're probably on the standard track. The Advanced track requires:
- 3 math Regents (Algebra I, Geometry, Algebra II)
- 2 science Regents (1 life, 1 physical)
- 1 additional LOTE (Language Other Than English) exam or 5-unit sequence in arts/CTE
- All at 65+
If you're missing any of those, you're not getting the Advanced designation. Period.
Step 2: Pick Your Science Sequence
Most schools follow one of a few common pathways:
Traditional:
- 9th: Living Environment
- 10th: Earth Science or Chemistry
- 11th: Chemistry or Physics
- 12th: Physics or AP/elective
Accelerated:
- 8th: Living Environment (Regents in June)
- 9th: Earth Science or Chemistry
- 10th: Chemistry or Physics
- 11th: AP Biology / AP Chemistry / AP Physics / AP Environmental
- 12th: Another AP or dual enrollment
Minimum Compliance:

- 9th: Living Environment
- 10th: Nothing (or a non-Regents science elective)
- 11th: Nothing
- 12th: Graduate with one Regents exam
That last one? It happens. It's legal. It also limits options.
Step 3: Pass the Lab Requirement
This trips people up. You cannot sit for a science Regents exam unless you've completed 1,200 minutes of hands-on lab time with satisfactory written reports. That's 20 hours. Not "I showed up." Not "I watched a video." Documented, graded lab reports.
Schools track this. If you're short, you don't take the test. You retake the course — or a lab make-up — next year.
Step 4: Take the Exam in June (Usually)
Regents exams are offered in January, June, and August. June is the main administration. January is for retakes or accelerated students. August is for summer school and retakes.
Scores come back in a few weeks. Practically speaking, " Below 65? 65 passes. 85 is "mastery.You can retake. The higher score stands.
Step 5: Apply for the Right Diploma
Your school submits your records to the state. You don't apply separately. But you should* verify your transcript before senior year ends. Errors happen. A missing lab notation. A score entry typo. Catch it in May, not July.
Common Mistakes / What Most People Get Wrong
"I Only Need One Science Class"
Wrong. You need one science Regents exam*. But New York requires three units of science credit for any diploma. That's three full years of science classes. You can't take Living Environment freshman year and then stop taking science. You'll run out of credits.
"Earth Science Doesn't Count as a Lab Science for College"
It does. It's a physical setting course with a lab component. Every SUNY and CUNY accepts it. Most private colleges do too. The "it's not a real lab science" myth persists because it's not chemistry or physics — but it meets the requirement.
"I Can Skip the Lab If I'm Good at the Content"
No. The 1,200-minute lab requirement is non-negotiable. The state audits schools. If you don't have the lab minutes documented, you're ineligible. There's no waiver for "I understand the material."
"Advanced Regents Just Means Better Grades"
It means more exams*. Different exams. Specific combinations. You can have a 98 average and still graduate with a standard Regents diploma if you didn't take the second science Regents or the third math Regents.
"AP Science Classes Replace Regents"
They don't
automatically satisfy the requirement. Practically speaking, an AP Biology or AP Chemistry course may be rigorous and college-level, but unless you also sit for and pass the corresponding New York State Regents exam—and complete the mandated lab documentation—it does not count toward the Regents science credential. If your school runs AP science without the Regents attachment, you will still need to register separately for the exam, often through a different course or as a self-contained test candidate. Some schools offer a combined AP/Regents track where the Regents is built into the sequence; others do not. Do not assume the transcript will sort this out on its own.
"January Exams Are Easier"
They are not easier. They are simply a smaller administration with a narrower pool of test-takers. The curve is set by that cohort, not by a fixed difficulty dial. Students who treat January as a low-stakes shortcut often underprepare and end up retaking in June anyway. Use January for genuine acceleration or a planned retake—not as a gamble.
"My Counselor Will Catch Everything"
Counselors manage hundreds of students. They are a safety net, not a guarantee. The most successful graduates treat their own graduation checklist as a personal responsibility: they print the requirement sheet, track each exam and lab unit, and confirm entries with the registrar each semester. Waiting for someone else to notice a missing Earth Science lab notation is how standard-diploma surprises happen in June.
A Note on Sequence Flexibility
New York's framework allows some rearrangement. A student strong in math might take Living Environment in 9th, Chemistry in 10th, and Physics in 11th, then use 12th grade for an AP or elective. Another might do Living Environment, Earth Science, then a dual-enrollment course. The law cares about total credits, exam count, and lab documentation—not the exact order, as long as prerequisites are respected and the diploma type is reached.
What it does not allow is gaps. Three science credits means three years of seated instruction. A student who finishes Living Environment and Chemistry by 10th grade still needs a 11th- or 12th-grade science entry, even if no further Regents exam is required for their chosen diploma. That third year is where minimum-compliance planners often slip.
Conclusion
The New York State science Regents path is less about intelligence and more about paperwork precision. The rules are public, the thresholds are fixed, and the exceptions are rare. Know your diploma type before 11th grade. Track your 1,200 lab minutes like money. Verify the transcript before the school year closes. And never confuse a hard class with a compliant one. A student who plans the sequence, respects the lab rule, and confirms the record will graduate with the diploma they intended—not the one they accidentally qualified for.
