Argh!!

I now actually feel I might make it to graduation.

If I just keep pluggin' away, one step at a time, and don't let up now, I think I can pass LPN School!! However, now I am freaking out about being prepared for NCLEX. I do my practice questions and ATI testing when I have time, but I do TERRIBLE. I try to think the question through....I pull out the obviously wrong answers (if there are any) and still I pick the wrong answer about 40-50 percent of the time. I average about 60-65 percent. Sigh. If I flunk the NCLEX, all this grief over the past year will be for naught, and bridging to RN will be a mute point.
Any words of wisdom or advice you'd like to impart? It'd be greatly appreciated.
