NYCLEX prep course

Hi,

I have a question and would to hear others thoughts on the ATI Course of study. My sister scored low on these tests but still passed her boards. Then I had a friend that had a 99.9 percent chance to pass her boards predicted by ATI and she failed. What do you think of the ATI course and their predictions if you pass or fail your boards? How well does their course prepare you for boards or is Saunders better? Anyone do the ATI? I am taking my boards next week and did not do well on the predictor test but it was hard for me to take for all the background noise I had going on. I live in an apartment. It stated I only had 78.8 % chance in passing and now I am stressed but my sister scored low and she passed. Please want to hear your thoughts. I really don't want to put off my test because the longer you wait the worse your chances are to pass it. I graduated last day of July from LPN school. My sister said the ATI study did not help her one bit. They suggest I put off my test for another month but I think I would rather take it and try. If you fail you can take it again in 45 days. Thoughts please????
