The Lpi 303-300 exam, officially titled LPIC Exam 303: Security, version 3.0, is the required test for earning the LPIC-3 certification, a credential at the Expert level. Passing it validates the skills Lpi expects from certified professionals, and it can also support progress toward related credentials such as LPIC-3 Security.
The 303-300 exam includes 60 questions, and you have 90 minutes to complete it. Before exam day, divide the available time by the question count so you know the pace you need to hold, and practice flagging time-consuming items for review instead of stalling on a single question. Timed sessions in the Actualtests4sure test engine are the easiest way to build that rhythm before it counts.
You need 500/800 to pass the 303-300 exam, and the official registration fee is $200 USD. Keep in mind that a failed attempt means paying that fee in full again for a retake, so avoid booking your seat on a hunch. Work through the Actualtests4sure practice test until your scores sit comfortably above the passing requirement before you schedule the exam.
