The Journey to OSCE

This repository contains a list of free or inexpensive resources that can be used as preparation for Offensive Security's Cracking the Perimeter (CTP) course and OSCE certification.

The following table shows notes, courses, challenges, and tutorials that can be used in preparation for the OSCE. It should be noted that the content within multiple sources do overlap each other so not all of these resources are needed.

The code located herein is associated with the various tutorials listed.

Sam Sanoop started this list and I noticed that there is more to be done!
