I agree with the others, I think Kaplan is a good resource, especially for new grads. If you can afford it of course. It's expensive. They also have an online option that may save you some money, but the course itself may be better in person.
I used the Kaplan CD7 and tested myself from that before taking it. It helps you to see where you stand and the questions are very similar in difficulty and the appearance. It it set up exactly the same with the background color and how the mouse works as the NCLEX exam. Great resource. If you can use that at least over a 2 week period working your way from the 75 question tests to the 265 question test a couple days before you sit for the exam, that's excellent prep.
Anything about 60% is a good indication you're where you need to be to pass. Also, something I've found is the lower you are in the 60's, the more questions you most probably will get. I was testing in the low 60's and got 202 questions, my friends were scoring in the high 60's to 70's and got less than 100 questions.
I agree Lippincott is also great because it breaks down the subject material, it has no index to reference which made me frustrated, so I just used my sticky notes to pick out those sections I could flip to easily and do questions.
Overall, build up your confidence while you study. Cover all the basics, like labs, VS for infants, kids, and adults, immunizations, etc. And then in each section of OB, Peds, Psych, and Med-Surg, study the Major abnormalities and disease processes. I can tell you the NCLEX will test you more on these situations than the more general subjects.
Good luck and CONGRATS on passing nursing school!
