Yes you can, and you should. After all, your future employment depends on it.
The test provider, Predictive Index, discusses the benefits of preparation on its website:
"Experience shows that if someone is used to these types of assessments, he or she will be able to get consistently closer to his or her ‘capacity’ or maximum score.
In other words, it is actually ideal when an assessment taker is trained or familiar with the PI item types, as it gives the company the best possible insight into the candidate’s true potential."
You can reach your full capacity within just a few days by preparing with our specially tailored PI test simulations and practice drills.
This way, by the time you take the test you'll be very familiar with the questions and format.
