Data Sufficiency Strategy

A free GMAT note on data sufficiency strategy: testing each statement alone before combining them, the five-outcome decision scheme our drills train, and the non-integer, negative, and zero cases that break hasty sufficiency verdicts.

  • Run the fixed evaluation ladder: statement (1) alone, statement (2) alone, and the combination only when both alone fail.
  • Stop each evaluation at determinacy — 'exactly one answer exists' — instead of computing the answer.
  • Stress-test quick verdicts with negative, zero, and non-integer cases before locking them in.

Formulas covered: Statement evaluation ladder · Five-outcome decision map · Sufficiency stress-test set

Critical Reasoning Strategy

A free GMAT note on critical reasoning: splitting arguments into premises and conclusion, the four common question jobs (strengthen, weaken, assumption, inference), the negation test for necessary assumptions, and the must-be-true standard.

  • Split a short argument into premises and conclusion, using indicator words where they exist and 'what am I being asked to accept?' where they do not.
  • Name the question's job — strengthen, weaken, necessary assumption, or inference — and state the standard of proof it imposes before reading options.
  • Apply the negation test to separate necessary assumptions from mere strengtheners.

Formulas covered: Argument anatomy map · Negation test · Question-job standards

Rates, Work, and Mixtures

A free GMAT quant note on uniform motion (D = rt), combined work through additive rates, and mixture problems as weighted averages, with the table setups that keep multi-agent rate problems honest.

  • Translate stated times and speeds into rates and organize motion problems in a rate-time-distance table built on D = rt.
  • Solve combined-work problems by adding simultaneous rates, including agents that oppose the job.
  • Set up mixture problems with number-times-value rows and solve for an unknown amount or concentration.

Formulas covered: Distance, rate, and time · Combined work equation · Mixture value equation
