Would that be enough to pass OSCP?

Ok, so, personally, I don’t think asking for help is a bad thing if you really need it. It is only bad if you mindlessly enter the command. Whereas, if you analyze the command, understand what it is you are running/doing to get to where you want to be, and you fully know how it works and why it works, then it isn’t anything to be ashamed of, especially since you can be sure you will not make that mistake again, and the next time you come across this problem or vuln, you know how to solve it.
