The documentation runs to several hundred pages and the video material lasts longer than 5min as well. Not to mention that the exercises in the documentation also take their time. Somewhat impatient, I then tried my hand directly at the lab.
That was a mistake. I wasted several hours on an attack that I could not carry out successfully. Afterwards I went back to the documentation. On page 305 I then found the decisive hint as to why my attack had not worked. Short cuts do not work with the OSCP.
My recommendation: skim the documentation. Watch the video. Read the documentation and do the exercises. In parallel maybe fire off a few scans (e.g. nmap or nikto) against the lab, but do not start hacking blindly.
