Triple-Task Capacity

Three unrelated tasks at once: this is the hardest exercise here by design.

Loading exercise...

Capacity tests are built to find your ceiling, the point where you can no longer add another task without something breaking. This exercise runs three unrelated channels at the same time, on purpose. One hand keeps a drifting crosshair inside a small centre box. Your ears follow a stream of spoken numbers that climb or fall by a fixed step, and you trigger every time that step changes and then hold the new step in mind. Your eyes watch a stream of coloured shapes and, whenever the target shape appears, you key its colour and its number. It is deliberately the toughest task on the site, so the guided practice layers the channels on one at a time, exactly the way candidates describe surviving the real thing.

About this test

What this test measures

This measures raw spare mental capacity: how much you can do at once before something breaks. Three unrelated channels run at the same time. One hand keeps a drifting crosshair centred, your ears track a stream of numbers and flag every time the step between them changes, and your eyes watch a stream of coloured shapes and report the target one by one. It is deliberately the hardest exercise on the site, because the real capacity tests are built to find your ceiling, not to be comfortable. What it scores is whether you can share attention across continuous control, a listening rule and a visual search without any one of them collapsing.

How to improve your score

  • Protect the tracking channel first: keep the crosshair moving with small, steady corrections so it never runs to the edge, because a lost crosshair is expensive and a late number press is cheap.
  • Turn each channel into a habit before you combine them. Use the staged practice (tracking alone, then tracking plus numbers, then all three) until the number rule and the shape response need rhythm rather than thought.
  • Do not chase perfection on any one channel. A steady share of all three beats a perfect crosshair with the numbers and shapes abandoned; when you feel yourself fixating, deliberately widen your attention back out.

Good to know

  • Protect the tracking first

    The crosshair is the only channel that punishes you continuously: let it run to the edge and you lose ground every frame until you recover it. The numbers and shapes are discrete, so a missed one costs a single response. When you feel yourself overloading, give a beat more to the crosshair and let a number or a shape slip; a steady share of all three always beats a perfect crosshair with the other two abandoned.

  • Layer the channels, do not juggle them

    Nobody runs three tasks by rapidly switching between all of them. Use the staged practice until the number rule (trigger on every change of step) and the shape response (colour then number) are automatic, so that in the scored phase your attention is spent on the tracking and the other two fire on habit. That layering is exactly how candidates describe getting through the real capacity test.

  • Real tests use dedicated hardware

    On-site capacity tests run on calibrated joysticks, headsets and custom coloured keypads that no browser exercise can replicate, so treat this as training for the underlying skill of dividing attention, not a replica of any machine. One practical tip from candidates who have sat the real assessments: practise with a mouse or a gamepad, not a laptop trackpad, because a trackpad makes smooth continuous control far harder than the real test ever would.

Frequently asked questions

Why is this the hardest exercise on the site?

Because the real capacity tests are designed to overload you until something gives, which is exactly how they measure spare mental capacity. We built this one to the same idea: three unrelated channels with no natural rhythm between them. If it feels like too much, that is the point of the format, not a sign you are doing it wrong.

How do I keep all three going?

Protect the tracking first, because a crosshair that runs to the edge is expensive to recover, while a late number or shape costs little. Let the number step and the target shape catch your attention rather than hunting for them. The staged practice exists so each channel becomes a habit before you have to run them together.

Is this exercise affiliated with any airline selection test or testing company?

No. This is an original SkyStudy exercise. The three channels, the rules, the shapes and the scoring are all built by us; it is not affiliated with any test publisher, airline or assessment centre, and it does not predict the outcome of any real selection.

I cannot hear the number stream. Can I still practise?

Yes. The numbers use your browser's built-in speech. If no speech engine is available, or you switch captions on, each number is shown as text instead, with the trigger rule unchanged. The shape channel is visual either way, so the exercise is fully playable and fully scored with the sound off.

How is it scored?

Each channel is scored on its own and then blended: tracking 40 percent, the number stream 30 percent, the shape watch 30 percent. Tracking carries the most weight because it runs continuously. The results screen shows every channel separately so you can see which one gave way first.

What hardware does the real version use?

On site a task like this runs on a dedicated station: a joystick or trackball with real inertia, a headset for the audio, and a custom keypad with coloured keys. A browser cannot replicate that, so treat this as training for the underlying divided attention rather than the hardware. If you have a gamepad, plug it in: the stick and the A button both work here.
