Most people do not finish. That is by design.

The PI Cognitive Assessment gives you 50 questions in 12 minutes. The average candidate finishes around 35 to 40 of them. The test makers know this. The structure is intentional. Speed is part of what is being measured.

So what actually happens to the questions you do not answer? Do they hurt you? Do they help you? Should you panic when the timer hits one minute and you have 12 questions left?

The short answers: blanks score zero, wrong answers also score zero, and you should never leave a blank. Here is the longer version.

How scoring works

Every question on the PI Cognitive Assessment is worth one point. There are no partial credits and no question-difficulty weights. A correct answer on question 1 counts the same as a correct answer on question 50.

Your raw score is the count of correct answers, from 0 to 50. That number is converted to a scaled score and a percentile rank against a norm group of approximately 288,000 test takers. The average raw score is around 20.

Importantly, there is no penalty for wrong answers. Some standardized tests deduct a fraction of a point for incorrect answers. The PI Cognitive Assessment does not.

Blanks vs guesses

This is the math that matters.

A blank answer scores 0 with 100% certainty. A random guess scores 1 with 25% probability and 0 with 75% probability, for an expected value of 0.25 points. On a four-option multiple choice question, every guess is worth a quarter-point in expectation.

If you have 10 unanswered questions and 30 seconds left, you have a choice. Leave them blank and earn 0 expected points. Click random answers and earn 2.5 expected points.

That is a meaningful score difference. Two or three points can shift your percentile by 5 to 10 points depending on where you fall in the distribution. For a candidate near a hiring cutoff, that is the difference between moving forward and getting a rejection email.

There is no scenario where a blank is better than a guess.

The final-minute sweep

Build this into your test plan. When the timer hits the one-minute mark, do this:

Stop trying to solve the current question (whatever it is)
Look at how many questions are left unanswered
Click an answer for every single one of them

If you have time after that, return to the questions you found hardest and reconsider. If not, the random guesses are already locked in and you have banked your expected 0.25 points per question.

The most common mistake on the PI Cognitive Assessment is not getting questions wrong. It is leaving questions blank when guessing was free.

Educated vs random guesses

If you have a few seconds per question instead of zero seconds, you can do better than random.

On verbal questions, eliminate obviously wrong answers (synonyms when looking for antonyms, off-topic words). With one wrong answer eliminated, your odds go from 25% to 33%. Eliminate two and you are at 50%.

On numerical questions, estimate the order of magnitude. If a question asks for the result of a calculation and the answers are 47, 470, 4700, and 47000, you usually know which range is correct even without doing the math.

On abstract questions, look for the answer that breaks an obvious rule. If three options follow a clear pattern and one does not, the odd one is sometimes right and sometimes wrong, but you have at least spotted the question’s logic.

Even 5 seconds per skipped question can move your guessing accuracy from 25% to 35% or higher. That compounds across 10 questions.

Why this is not cheating

Some candidates feel weird about random guessing. They worry they are somehow gaming the test or that the scoring will punish them.

It will not. The PI Cognitive Assessment is built around the assumption that candidates will guess on what they do not know. The norm group of 288,000 test takers, the comparison data your score gets benchmarked against, includes plenty of candidates who guessed on their final questions. Your guesses do not make your score artificially high. They make it accurate.

The candidates who leave blanks are the ones with artificially low scores.

What unfinished says about you

The PI Cognitive Assessment results that go to your employer do not say “candidate did not finish 12 questions.” They show your score and percentile. The employer does not know if you finished or not.

What they see is a number. Your job is to make that number as high as possible. Skipping is fine. Leaving blanks is not.
