Does NCSBN Learning Extention help passing NCLEX-RN?

Hi Guys,

I was just wondering if you guys found the NCSBN Learning extension helpful. I just purchased it today and have done really horrible on all the pretests...the questions are really difficult.

For those of you who have passed NCLEX and used learning extension did you have any similar questions or content on NCLEX, or did it just help with how to answer the questions.
