Start the test

The clock starts as soon as you click. Your paper is drawn fresh, so a second sitting is a different set.

Proctored sitting

  • Laptop or desktop only, with a webcam. Phones and tablets can't start a test.
  • The test runs full screen, with the site's navigation hidden.
  • Your webcam stays on and is checked on your computer — nothing is recorded or uploaded.
  • Leaving full screen, switching tab or window or minimising blurs the paper — and so does the camera seeing no one, someone else, a phone, or you looking away. The clock keeps running.
  • Each is a warning; the third ends the sitting. It is graded so you can review it, but marked disqualified and never counted as your best.
  • Pasting, copying, right-click and printing are off.

Before you start

A single thirty-minute section mixing quantitative, reasoning and verbal, at roughly the pace of a services paper.

  • One minute a question. That is the pace every services test expects.
  • No negative marking.

Short enough to sit before an interview, long enough to be honest about your speed.

Instructions

A single thirty-minute section mixing quantitative, reasoning and verbal, at roughly the pace of a services paper.

  • No negative marking.

Short enough to sit before an interview, long enough to be honest about your speed.

How to prepare for this pattern

A guide to CodeKairo's thirty-minute sprint: a single mixed section at the pace services papers expect, for the days you only have half an hour.

What the paper looks like

One section, Mixed Aptitude: 30 questions in 30 minutes, twelve quantitative, ten logical and eight verbal. Each question is worth one mark and there is no negative marking. With a single section there is nothing to lock, and you can move between questions freely until the clock runs out. The paper is not adaptive. It is not a company pattern but a short diagnostic at services-paper pace: one minute a question, the pace every services test expects. It is short enough to sit before an interview and long enough to be honest about your speed.

How to prepare, section by section

Sit it regularly and compare your results. If your score rises but you still run out of time, speed is the gap, and the topic pages above are the place to drill it. If you finish with time to spare but still miss questions, slow down and check. When you want the full two hours, take the Full-Length Aptitude Paper; when you want a particular company's shape, sit its own pattern.

On the day

A minute a question means no single question deserves more than two. Make a first pass answering everything you can do in under a minute and skipping the rest, then use what is left on the skipped questions, the quickest-looking first. With no negative marking, put an answer against every question before the thirty minutes run out, even if the last few are guesses. Afterwards, look at which kind of question you skipped most often: that is where your next half hour of practice should go.

This sprint is not modelled on any company's published pattern but is CodeKairo's own short diagnostic at services-paper pace, and CodeKairo is not affiliated with any employer.
