Kaplan is great
I also did the complete online one for $450 and I took the NCLEX today and am GLAD I took that class. (test was still very hard, but i felt much more comfortable than i would have otherwise)
It teaches strategy and goes over the most commonly tested nursing content on the NCLEX. Goes over every body system, meds, etc. Very comprehensive.
Also, you can get your $$$ back if you fail! Guarantees you will pass (if you take Kaplan and NCLEX within 6 months of graduation, and i believe there's some other fine print)
I'll let you know if it was worth the $$$! My test cut off @ 75, so its either real good or real bad
Kaplan was the only thing I used to review for NCLEX
