I'm sorry you're in this situation Although doing a remediation course is not ideal, I think it will be extremely helpful to you. If you fail a 4th time, there is either a large amount of knowledge you are missing (you have to have a really in-depth knowledge), or you're not studying the right way. Your educators might be able to figure out an ideal study plan for you. I think it would be helpful to get a personal tutor if this is the case.
Also, do you have a psychological disorder that might be hindering you? For example, if you have crippling anxiety regarding the NCLEX, you might have to treat that first. You can have all the knowledge in the world, but you can fail the NCLEX again if you are just too anxious to focus.
If it makes you feel better, I thought I completely bombed the NCLEX as well when I took it. I think most people feel that way, regardless of whether they passed or not. Don't give up! I know you can do anything you set your mind to!!
