Cramming right before the test feels productive but hides your real gaps. A full-length mock now diagnoses which NYS categories you're weakest in — so you can focus your study only where it counts. Learning science is clear: retrieval practice and spaced study beat last-minute cramming. Starting earlier is the higher-scoring path.

Learn the Concepts

Visual lessons that build 幾何学 from first principles — diagrams, worked examples, embedded practice.

Parallel Lines & Transversals: The Eight Angles, Three Rules

When a transversal cuts two parallel lines, eight angles appear — but they're really just two values repeating. The three rules that turn every angle problem into a one-step calculation.

The Pythagorean Theorem: One Equation, Half the Geometry Regents

The most-tested theorem in New York Geometry, derived visually. Find missing sides, recognize the five triples by sight, and avoid the two classic traps that cost students easy points.

Special Right Triangles: 30-60-90 and 45-45-90 Without a Calculator

The two right-triangle shapes the New York Regents loves to test. Memorize one ratio for each and skip the Pythagorean arithmetic on roughly 1 in 6 Geometry questions.

Triangle Congruence & Similarity: SSS, SAS, ASA, AA and the Famous Traps

When are two triangles identical, when are they just scaled copies, and why do AAA and SSA never prove congruence? The five valid rules, the AA shortcut for similarity, and the k² / k³ area-and-volume scaling rule.

What Students Are Saying

"
Took the Geometry Regents and felt genuinely ready. The practice here covered the same topics in the same format, so nothing on the exam caught me off guard.

I crammed the week before and just barely passed. The full-length mock exams matched the real format, and the step-by-step explanation on every question is what saved me. If I did it again I'd start way earlier and use a mock to find my weak spots first, instead of cramming everything at the end.

幾何学 Regents — Common Questions

How much time do I need to study before the Geometry Regents?

It depends entirely on your starting point. A typical student benefits from 2–4 weeks of consistent practice (15–30 minutes a day) covering coordinate proofs, similarity, right-triangle trig, and circles. One NY Regents Quiz™ user — an 8th grader accelerating into Geometry — recently passed after only 2 days of focused review on the platform. We don't promise that pace; we point it out so you know the prep can be efficient when it's targeted at the NYS the exam actually tests.

How hard is the Geometry Regents?

The Geometry Regents expects fluency with proofs, coordinate geometry, transformations, similarity, right triangle trigonometry, and probability. Visual reasoning and the Pythagorean theorem appear repeatedly. Students who consistently hit 80%+ on our mock exams typically pass their first attempt.

What topics are on the Geometry Regents?

The exam covers all five NYS reporting categories: Coordinate and Transformational Geometry; Logical Argument and Constructions; Proof and Congruence; Similarity, Proof, and Trigonometry; and Two-Dimensional and Three-Dimensional Figures plus Probability. Each is sampled across Semester A and B mock exams.

How long is the Geometry Regents?

The official Geometry Regents runs about 3 hours with roughly 50–57 questions, including diagrams and coordinate-plane problems. Our mock exams replicate this length and visual question style so your timing practice is realistic.

Do I need a calculator and a ruler for Geometry Regents?

Yes — a graphing calculator is permitted, and you may need basic geometric tools depending on the testing center's policy. Our practice questions provide the same diagrams and coordinates so you can train using on-screen reasoning.

Is the Geometry Regents harder than Algebra 1?

Most students find Geometry trickier because it requires both algebraic skill AND spatial/proof reasoning. The questions involve more diagrams. Our weak-point retargeting catches whether you struggle with proof logic, coordinate work, or trigonometric ratios — so prep time is spent where it matters.

What is the passing score for Geometry Regents?

A score of 65 passes, and 85 or higher earns Mastery level — the same scoring as all New York State Education Department Regents exams. Aim for 85+ on full-length mocks to give yourself a buffer against the harder proof-style questions on the official exam.
