Rescheduled My Nclex

Well I rescheduled my test for my second nclex-pn. I really wasn't ready I work 3rd shift and I was not feeling ready at all. My review test score were very low in the 40% to 50% scores. I just have a lot on my plate this week and I wasn't feeling ready at all. I need to go over a lot of things to feel comfortable with them. I had almost all near passing on my test in March but failed. I haven't been feeling ready for a few days now but I was going to just go take the test but something inside of me said NO be ready . I need my scores on my review to be in the 70% to 80%.. I am using Hurst review, Saunders for nclex-pn..I love the review but my scores are bad ...and I didn't feel ready:no:. My life is all about the nclex so I think I need a break for a few days and regroup . Is this normal to feel this way..?
