Abstract reasoning test on one clock across the whole set

In publishers' catalogues the three names overlap heavily, and which one appears in your invitation email tells you less than you would hope. Abstract reasoning and inductive reasoning are usually the same figural task under two labels; diagrammatic reasoning is more often the one with process flows and operators in it, and is more common for software and engineering roles. The safe assumption when you are told to expect one of them is that you will see shapes changing according to a rule you have to infer, and that the differences between the three names are marketing rather than construct.

Nothing does, and the reason is structural rather than modest. A cut-off would have to come from somewhere, and the only somewhere available is this page's own choice of how hard to make twenty items — move one rule and the same person scores three marks higher. What a publisher sells is not the item bank but the comparison group behind it, and the same raw score converts to different percentiles against graduate applicants, against managers and against one employer's own applicant pool. The figure worth carrying away from a practice run is not the count but the pace: how many items you finished before the clock, and whether the ones you lost were lost to the rule or to the time.

On a set with no negative marking, always. A blank is worth exactly zero and a blind guess is worth the reciprocal of the number of choices, so across a run the arithmetic is unambiguous. The only situation that reverses it is formula scoring, where a fraction of a mark is deducted for a wrong answer to cancel the value of guessing — that is rare in graduate testing and, where it exists, the instructions say so explicitly. If the instructions do not mention a penalty, there is not one.

Because twelve minutes is the shortest budget that reproduces what the clock does to you, and a short run is one you will actually take twice. Pacing pressure appears as soon as the average per item drops under about a minute; it does not get more instructive at twenty-five minutes, it just costs more of your evening. What a longer sitting does add is fatigue, which is a real component of a long assessment and is deliberately not measured here.

Because the version of this format you are likely to meet does not let you either, and building in a review screen would train a habit the real thing punishes. Forward-only delivery is the norm for computer-administered aptitude sets, partly to stop candidates working the whole paper backwards from the easy items and partly because the item is meant to be answered from what is on the screen. If you want to go back over your reasoning, the untimed sibling pages keep every item for review at the end.

It runs on frames the browser actually delivers to this tab, so a stutter of a few dropped frames costs you those milliseconds and nothing more, and a switch to another window costs you nothing at all — the item you were on is thrown away instead. That is more generous than a real administration, which typically keeps counting and often reports the switch to the employer. It is the right trade for a practice page: the number here should describe your reasoning, not your notifications.

They come from the same generator with the same five construction rules, and every run draws fresh items from a new seed, so you will not meet an item twice unless you reuse a seed deliberately. That matters more than it sounds: an item you have already solved measures recall rather than reasoning, and a practice site that served everyone the same twenty items would be measuring how many times you had visited it.
