I recently bought Delmar "Practice Questions for NCLEX RN"
and took the first test today with this program (175 q)
and what can I say - wow! it's excruciatingly difficult most of the time. I normally scored at about 80-90% in Saunders and Springhouse programs (I started with them) - those are piece of cake, and I scored only 61% in Delmar, I felt like I didn't know anything and was guessing all the time, lots of "none makes sense" and "all make sense" answers, and some "i don't understand what they're asking me" ones...
Delmar is as hard or even harder than Kaplan (I took one test from their question trainer about a month ago) except that Kaplan doesn't seem to ask basic knowledge questions (Delmar did a couple of times).
It's also a new release, so there are lots of "choose all that apply" and "type-in" answer questions, and also a few about cultural influences, community/home care etc... Another bonus is that the pool contains about 4400 questions, so it will take a while to go through all of them. You're given statistics after completion of the test.
The bad point is that you can't really choose areas to study. There's only one option "random test". But Kaplan doesn't allow it either so... not a big deal to me... I stumbled upon several questions with unclear rationales and errors in the answer choices (missing lines, corrupted), but those were about 4-5 of them... the rest seemed to be pretty accurate and complete.
The CD also contains animations and instructions on IV techniques... not bad.
I highly recommend this book/CD. I think it deserves some attention to say at least.
