GMAT Arithmetic and Algebra Preparation Guide

Begin with the current official scope. Quantitative Reasoning contains 21 Problem Solving questions in 45 minutes, and the section uses foundational arithmetic and elementary algebra. The official exam-content page emphasises logic and analytical skill, not advanced mathematics, and says a calculator is unavailable in Quant. Data Sufficiency belongs to Data Insights, not current Quant. A preparation plan should therefore prioritise useful relationships, mental estimation, written organisation and answer-choice evaluation instead of obsolete question families or calculator-dependent drills.

Run a diagnostic by domain and by cause. Arithmetic coverage should include integers, divisibility, primes, factors, multiples, fractions, decimals, ratios, proportions, percentages, averages, weighted averages and rates. Algebra coverage should include expressions, equations, inequalities, systems, exponents, roots and translating words into variables. For every miss, record whether the cause was concept knowledge, target identification, units, an unstated assumption, setup, sign handling, computation, answer-choice interpretation or time. Two students with the same accuracy may need completely different lessons.

Practise arithmetic as relationships rather than disconnected tricks. A ratio compares quantities; a percentage describes a base; an average depends on both total and count; a rate connects amount and time. Write the base, units and requested value before calculating. Reduce fractions and estimate size so an impossible answer is visible early. When answer choices are widely spaced, official mba.com strategy advises considering approximation before committing to long computation. Estimation should be a reasoned check, not a guess that replaces the exact requirement.

Treat algebra as a language for unknown relationships. Define variables clearly, translate one phrase at a time, preserve inequality direction and test whether the result satisfies every constraint. Compare direct solving with substitution, logical cases, back-solving from answer choices and plugging in valid numbers. The best method is the simplest one that remains logically complete. A familiar-looking formula can fail when the question changes the base, unit or condition, so students should explain why each step is allowed rather than reproduce a memorised sequence.

Build a review cycle that separates accuracy from speed. First solve small official-format sets without a clock and write the target, relationship and method. Next repeat the same domain with a moderate time budget, then mix arithmetic and algebra so topic recognition is no longer obvious. Review wrong, guessed and slow correct answers. For each, state the original error, corrected reasoning, faster alternative and one new transfer question. Finally, use section checkpoints and full simulations so Quant pacing does not damage Verbal or Data Insights preparation.

MKS Education offers GMAT preparation through physical, online and hybrid classes in Kathmandu. Students receive recordings in every mode, iOS and Android app access through the MKS GMAT platform, physical books and teacher feedback. The guided course runs for eight weeks, while class and practice access continues for six months with continued support. A student who needs another suitable explanation may attend suitable repeat classes without another class charge, subject to current schedules and seats. MKS does not guarantee a score, admission, scholarship, assistantship or funding.
