Finally got OSCP few days ago, it is the most interesting course I ever had. Back to early July, I got the lab notes and video, and 3 months of virtual lab access. From information gathering, mapping, vulnerability identification, exploitation and post exploitation, the course gave you the knowledge and mindset (in terms of technique) of what a pentester should be.
The most valuable part of the course is the lab, the lab contains around 60 machines with different types of vulnerabilities, your goal is to root the machines. After playing for the labs for two months, eventually able to get all the labs rooted. Some of the labs like sufferance, humble, gamma, observer are particularly more interesting than the others, you need extra efforts in order to root them. I am not going to give any spoilers here, you can PM me here or in the offensive-security forum (alanh0 is my nickname there).
For the exam, as long as you have studied the lab notes, and able to root the machines in the lab on your own, you should be able to pass the exam. There are few types of questions in the exam, make sure you get the easiest one and confident one first, not to struggle in one target for few hours, it will be better for you to do a cycle like 1 to 2 hours for each target, and take some breaks in between, even though you are confident, you still need some rest :)
Good luck buddies!
