At the college I am currently teaching clinicals, we use ATI as a tool to assist the students in NCLEX test preparation. Overall, I think it a good product, however, it has to be used.
Well, did you know they have a Facebook page that has a weekly question?? How cool is that! They post a random question every week and then the rationale at the end of the week. Whether you area student or a nurse practicing since the dinosaurs, I think it is a great tool to stay sharp! Check it out and keep that brain exercising!
