Oscp is acutally considered being the entry level of penetration testing. It’s not the hardest exam ever but not the easiest either. There is a cheatcheet that you could use to practice: NetSecFocus Trophy Room - Google Sheets. Here, you will find OSCP like machines, so if you can do them without any problem, you are most likely ready for oscp. But on the other hand, if you can’t do them, then you should wait some time before taking the oscp.Hope that helps
