Get a book by Diana Rupert called NCLEX Alternative Format Questions. I thought this book was helpful with SATA etc... I did take Kaplan and passed on the first try. The whole method is based on using the decision tree, but honestly I was unable to apply it during the exam, however, it made perfect sense during the class? Anyway, I think it was the Kaplan study questions that helped me the most but I paid a pretty price for them. Best of luck to you! You will get it the second time for sure!
