Problem Solving: The GAN Aptitude Test Section, Explained

Problem Solving is 35 word problems in 35 minutes: the same arithmetic as the computation section, wrapped in a practical scenario. Rates, unit costs, material quantities, time, and measurement. The arithmetic is rarely the hard part — the setup is.

That is a full minute per question. This section is one of six on the battery, which runs about 140 questions in roughly two hours — see the full GAN aptitude test breakdown for how the whole thing fits together.

What this section measures

Whether you can turn a described situation into a calculation. That translation step is the actual job skill: a foreman describes a run, and you work out the material.

Whether you keep track of units and of what the question actually asked for, under time pressure, without a calculator to lean on.

How to train it

Write the setup before you compute anything

One line: what you are solving for, and the relationship that gets you there. Most wrong answers on this section are correctly-executed arithmetic on the wrong equation. Thirty seconds of setup saves the whole question.

Underline what is actually being asked

Overtime problems that ask for the number of overtime hours, not total pay. Material problems that ask for the cost of one, not the total. The answer choices will happily contain the value you would have got by answering the question you assumed.

Track units through the calculation

Dollars per foot times feet gives dollars. If your units do not come out as the thing being asked for, your setup is wrong and no amount of careful arithmetic will save it. This catches setup errors before you spend time computing.

Use proportions for anything that scales

If 3 lengths of pipe cover 24 feet, then 7 cover 56 — set it up as a proportion and cross-multiply rather than finding a unit rate and multiplying back up. Fewer steps means fewer chances to slip.

Where applicants lose points

  • Answering the intermediate value instead of the final one — solving for 3x and reporting 18 when x = 6 was wanted.
  • Overtime and percentage problems where the base changes: a 20% discount off a 65% markup is not a 45% markup.
  • Mixed units in a single problem — inches and feet, minutes and hours. Convert first, once, and write it down.

Frequently asked

What kind of word problems are on the UA aptitude test?

Practical arithmetic: hourly pay and overtime, unit costs and totals, material quantities, rates of work, time, and measurement conversions. Nothing beyond basic algebra.

How long do I get per question in the problem-solving section?

Thirty-five questions in thirty-five minutes — exactly one minute each on average. Some are ten-second reads; budget the time you save on those for the multi-step items.
