The OSCP Exam: What to Expect and How to Succeed

Alright, you've done the work, you've prepared, and now it's exam time! The OSCP exam is a 24-hour practical exam followed by a 24-hour report-writing period. Here's what you need to know to succeed:

Exam Format and Structure

The exam consists of compromising several machines in a simulated network. The number of machines and their complexity vary, but the goal is always the same: gain access to the machines and obtain the required flags (proof.txt files). You'll be given a set of instructions at the beginning of the exam. Make sure you read them carefully. The machines are designed to challenge you and test your skills. They're not meant to be easy, so don't get discouraged if you get stuck. Take breaks, regroup, and try again. It's a marathon, not a sprint. The exam will test your ability to think critically, solve problems, and document your findings. Don't expect to breeze through the exam. It requires persistence, patience, and a willingness to learn from your mistakes. You'll be assessed on your ability to: identify vulnerabilities, exploit systems, escalate privileges, and document your findings. This is a real-world test, and it requires real-world skills. The exam is divided into several sections, each with a specific objective. You'll need to complete each section to pass the exam. The exam is graded based on the number of points you earn. You need to achieve a certain number of points to pass. The points are awarded based on the machines you compromise and the flags you obtain. The more machines you compromise, the more points you earn. There are some machines that are worth more points than others.
