Anyone recommend NCSBN's online self-study?

I'm using NCSBN for 2 weeks now (I purchased the 3-week plan) and I'm really loving it! :) Closer questions to NCLEX I must say - I already took nclex last 2010 and sadly I failed so I would know the type of questions. I've also used Kaplan Strategies and Qtrainers, and they are a little harder than NCSBN. They can really build up your critical thinking.

what about the difficulty level of the ncbsn questions compared to NCLEX/KAPLAN, and do they give you rationales for right/wrong answers with all the questions?

For the NCSBN, they only give the rationales for the right answers. But it's a very clear rationale, so you wouldn't need to know why the other options are incorrect. For the Kaplan Qtrainers, yes they are giving rationales for right/wrong answers.

i used the ncsbn and i passed the nclex the first time. i did it in 5 weeks; the first 4 weeks, i read over most of the review and the last week, i focused on doing as much as the questions as i could. the only thing i did not like about it was they only give you the rationales for the right answer on the questions. i also used saunders and the kaplan strategies book. i do think that the questions from the ncsbn are most like what is on the nclex.
