The NY Earth Science Regents: Format, Reference Tables & How to Study
The Physical Setting/Earth Science Regents is one of New York's most diagram-rich science exams — it rewards students who can read maps, charts, and cross-sections quickly and who know the Earth Science Reference Tables inside out. Here is exactly what to expect and how to prepare.
What it is — and the lab requirement
The exam is given by the New York State Education Department at the end of a year-long Earth Science course. One detail catches students off guard: to even sit the exam, you must first complete a minimum of 1,200 minutes of hands-on laboratory work with satisfactory written lab reports on file. No labs, no exam — so keep up with them all year.
How the exam is structured
The written test runs three hours and is worth about 85 points, split across several parts:
- Part A and Part B-1 — roughly 50 multiple-choice questions on core content.
- Part B-2 and Part C — constructed-response questions where you read data, label diagrams, calculate, and explain in writing.
- Part D — a lab-based component built around hands-on skills (mineral identification, contour maps, and similar stations).
So a little over half the exam is multiple-choice. Those points are the fastest to lock in, which is why focused multiple-choice practice moves your score most efficiently.
Your biggest score lever: the Reference Tables
Every student is given the Earth Science Reference Tables (ESRT) — a booklet of charts and formulas you may use during the exam. Students who know it cold have a real advantage. It contains, among much else:
- The key formulas — eccentricity = distance between foci ÷ length of major axis, gradient = change in field value ÷ distance, rate of change, percent deviation, and density.
- Charts for identifying minerals and rocks, planetary data, properties of water, and dewpoint / relative-humidity tables.
- The geologic history of New York State and a generalized landscape-regions map.
Practice using the ESRT, not just memorizing facts — many questions are really asking, "can you find and apply the right chart?"
What is tested
The content falls into a handful of big areas:
- Astronomy and Earth's motions — seasons, eclipses, eccentric orbits, the expanding universe.
- Mapping and Earth's dimensions — topographic maps, latitude and longitude, gradient, Earth's true shape.
- Meteorology — air pressure, station models, fronts, humidity, and the water cycle.
- Minerals, rocks and plate tectonics — the rock cycle, plate boundaries, earthquakes, and volcanoes.
- Surface processes and landscapes — weathering, erosion, deposition, and how landforms develop.
A smart way to study
- Learn the ESRT first. Spend an afternoon mapping out every chart so you can find anything in seconds.
- Drill the diagrams. Eccentricity ellipses, station models, contour maps, and geologic cross-sections show up again and again.
- Practice multiple-choice under time, then review why each answer is right or wrong — that review is where scores actually climb.
- Aim well above a raw 65. Because of the raw-to-scale conversion, a comfortable margin protects you on exam day.
