What you will actually face
Most questions hang off a chart or a table you have to read before you can answer, and the clock keeps running while you read it.

Can I use a calculator?
Usually yes on a numerical test and often no on a cognitive one. SHL builds its numerical tests on the assumption that you have a calculator. Many CCAT administrations do not allow one. The employer sets the rule, so read your invitation email and the instruction screen before you start.
How long does each test take?
Between 15 and 40 minutes for most graduate tests. SHL Numerical Ability is 16 questions in 20 minutes, SHL Verify G+ is 30 questions in 36 minutes, the CCAT is 50 questions in 15 minutes, and the Watson Glaser is 40 questions in 30 minutes. That works out at anywhere from 18 to 75 seconds per question.
What counts as a good score?
There is rarely a fixed pass mark. Your raw score is turned into a percentile against a norm group and the employer sets the cut for the role. For a competitive graduate scheme, the top third of candidates is a sensible working target.
How does norm group scoring work?
The publisher tests a large comparison sample and reports where you sit inside it. A percentile of 70 means you scored higher than 70 percent of that group. The same raw score can therefore read differently against a graduate norm group and against a general population one.
Can I retake an SHL test?
That is the employer's decision, not SHL's. Many employers allow one attempt per application cycle and treat a score as valid for around a year, so a weak result can follow you into your next application. Later in the process you may also sit a supervised verification test that confirms your unsupervised score.
Does practice actually raise the score?
It raises speed and cuts avoidable errors, which is where most marks are lost. It does not change your underlying ability. What it removes is meeting the answer format for the first time on the live test, and losing track of the clock.
Should I guess when the clock is running out?
Yes on most tests. They score the number of correct answers with no deduction for a wrong one, so a blank is strictly worse than a guess. Check the instruction screen first, because a small number of tests do apply a penalty.
