Lydia,
Thanks for this post. NBCSN has become aware of many exam prep items that are being marketed for the exam that are of poor quality. Although it is a free market and we cannot control what others publish, NBCSN has posted recommended resources on our website. We have vetted these resources. Most concerning is the name of the company Pass4sure.com. No one can guarantee that any exam prep material will ensure a candidate's success. Buyer beware!
