GMAT Quant Drill Book

The GMAT Quant book that doesn't waste your time.

If you're aiming for 700+ and you're tired of practicing questions that are too easy to teach you anything, this is the book you've been looking for.

The Sutras Quantitative Drill Book contains 400 original, Hard-to-Very-Hard GMAT Focus Edition questions organized into five precision-targeted topic modules. Every question comes with a complete explanation — not a one-liner, a full worked solution that shows the algebra, names the concept, and explains exactly why the wrong answers are wrong.

THE FIVE MODULES:

① Number Properties — Divisibility rules, remainder arithmetic using modular logic, prime factorization, units digit patterns, LCM/GCD, and counting problems. The module most test-takers underestimate.

② Algebra — Quadratic equations, systems of equations, inequalities (including absolute value), function notation, sequences (arithmetic and recursive), and exponent manipulation. Every question has a faster path — the explanations show you how to find it.

③ Geometry — Lines and angles, triangle properties (including the three must-know special triangles), circles (sector, chord, tangent), coordinate geometry, 3-D volumes and surface areas. Difficulty spikes at coordinate geometry and circle theorems.

④ Statistics & Rates — Mean, median, mode, range, standard deviation, weighted averages, combined work rates, distance-rate-time (including relative speed and the harmonic mean shortcut). The most calculation-intensive module.

⑤ Word Problems — Percent change, successive percent changes, markup and discount, mixture equations, Venn diagram overlapping sets (two and three groups), simple and compound interest, ratio and proportion. The module where careless translation errors cost the most points.

EVERY QUESTION INCLUDES:

• Difficulty level (●●●○ Hard or ●●●● Very Hard for 75% of questions)
• Sub-topic tag so you know what concept is being tested
• Full worked explanation with algebraic setup
• Analysis of wrong answer traps on Very Hard questions

COMPLETE ANSWER KEY — All 400 answers organized by module in a clean reference grid.
