NAPOLCOM exam quantitative reasoning reviewer: math, by topic.
Quantitative reasoning is the area most examinees fear and the one that responds fastest to practice, because the methods are concrete and the range of item types is small. The exam does not test advanced mathematics. It tests whether you can do secondary-school arithmetic accurately and quickly under a clock, and whether you can turn a short word problem into the right calculation. Each topic below has its own reviewer.
What this area tests
Quantitative reasoning tests arithmetic and basic algebra done by hand: operations on whole numbers, fractions and decimals, percentages and ratios, word problems, and number patterns. No calculator is allowed, and the items are built around numbers that reward estimation.
- Arithmetic and basic algebra by hand; no calculator on exam day.
- Estimation eliminates two of four options on many items before you compute.
- Word problems reward recognising the type before touching a number.
- Number sequences are pattern-spotting that improves with short, frequent drills.
Topics in this area
NAPOLCOM Exam Basic Operations Reviewer: Arithmetic, Fractions and Percentages
The arithmetic the NAPOLCOM quantitative area tests with no calculator: order of operations, fractions, decimals, percentages and ratios, with by-hand shortcuts.
NAPOLCOM Exam Word Problems Reviewer
The word problem types the NAPOLCOM quantitative area uses (rate, percent, ratio, average, age, work) with the setup for each and worked examples solved by hand.
NAPOLCOM Exam Number Sequence Reviewer
How number series items on the NAPOLCOM exam work: arithmetic, geometric, squares, primes, alternating and two-step rules, with a checklist to run on every series.
How to study this area
Make the fundamentals automatic first: times tables, fraction-decimal-percent conversions, and the common shortcuts for percentages and ratios. Every second saved on routine arithmetic is a second kept for the word problems, which is where the area is won or lost. Drill by hand from the start, because that is how you will sit the paper.
Estimate before you calculate. The items use round numbers and clean fractions precisely because nobody has a calculator, so round each value, get a rough answer, and check it against the four options. On a large share of items that alone eliminates two or three choices. For word problems, read the last sentence first to find what is being asked, name the type (rate, mixture, work, age, percentage change), then set up the calculation.
Common mistake. Solving the wrong quantity: computing the part when the item asks for the whole, or the discount when it asks for the final price. Underline exactly what is asked, and the unit it is in, before you start any arithmetic.
Recommended order
- 1
Basic operations and fractions — the foundation everything else stands on.
- 2
Percentages and ratios — the most frequently tested applications.
- 3
Word problems — the largest share of points; practise recognising the type.
- 4
Number sequences — pattern-spotting that rewards short daily drills.
