Quantitative — Data Sufficiency for the GMAT Exam — New York candidates

12% of the GMAT test plan. Determining whether two statements, individually or combined, provide enough information to answer a question — without solving it. Calibrated for New Yorker candidates.

Examiners do not award marks for content alone — they award them for the ability to demonstrate competency in the precise format the test demands. Quantitative — Data Sufficiency sits at roughly 12% of the Graduate Management Admission Test content distribution — Data Sufficiency (DS) is unique to the GMAT and the most conceptually different question type most test-takers encounter. The goal is NOT to find the answer — it is to determine if the answer CAN be found. Candidates who try to solve DS questions like PS questions waste time and make systematic errors. Pass rates for the GMAT are published annually by the awarding body and vary by cohort and locale. For New York candidates preparing for GMAT, the calibration of study to local context matters: New York is a top-3 state for NCLEX-RN, MCAT, and GRE candidates. NY State Education Department (NYSED) handles RN licensure differently from compact states.

Pass rates for GMAT (New York, USA) are published periodically by the awarding body.

Common failure modes

These are the patterns that cause most candidates to lose marks on this topic. Recognising them in advance is half the work.

  • !Solving for a specific numerical value instead of testing whether a unique answer is possible
  • !Forgetting that Statement 2 must be evaluated independently before testing both together
  • !Assuming constraints from Statement 1 when evaluating Statement 2 in isolation

Study tips

  • 1Memorize the five DS answer choices and their logic (A, B, C, D, E) before test day — eliminate systematically.
  • 2For "is X > 5" type questions, find cases where X > 5 AND cases where X ≤ 5 to prove insufficiency.
  • 3Never re-use Statement 1 when evaluating Statement 2 — treat them as completely separate universes.
  • 4For NCLEX-RN: NYSED is not part of the Nurse Licensure Compact, so a NY licence does not transfer to other states without endorsement. Consider this if you plan to work in NJ/CT after graduating.
  • 5For MCAT: most NY medical schools (Columbia, Cornell, Mount Sinai, NYU) cap MCAT scores accepted at 3 years old — verify your target schools' exact policy.
  • 6For CDL: NY DMV requires a 14-day permit-holding period before scheduling the CDL skills test; budget this gap into your training schedule.

Sample GMAT Quantitative — Data Sufficiency questions

These sample items mirror the format and difficulty of real GMAT questions. Practice with thousands more on the free Koydo question bank.

  1. 1

    Is integer n divisible by 6? (1) n is divisible by 12. (2) n is divisible by 9.

    • AStatement (1) alone is sufficient, but statement (2) alone is not sufficientCorrect
    • BStatement (2) alone is sufficient, but statement (1) alone is not sufficient
    • CBoth statements together are sufficient, but neither alone is sufficient
    • DEach statement alone is sufficient
    Why this answer?

    If n is divisible by 12, it is divisible by all factors of 12, including 6. So Statement 1 is sufficient. Statement 2 alone: n could be 9 (not divisible by 6) or 18 (divisible by 6) — insufficient. Answer: A.
