Format of PATI

You can expect to encounter a Paper & Pencil test with a multiple-choice format. The time frame for PATI is 1.5 hours plus an additional 15 minutes to accommodate the administration of the test.

Keep in mind that scores are comprised solely of correct answers. Since there is no penalty for wrong responses, it is to your benefit to answer every question; guess if necessary.
