give you free (print or downloadable) content guides for each exam, and the CPNE study guide is also included in tuition. Books and supplemental stuff is not included. TCN, RUE, Chancellors, etc are extra and not affiliated with the college (though they try to claim to be which confuses students). If I was an educator I could sell supplemental guides and learning tools specific to Excelsior college too. Well, I could do so even if I am not an educator! Like Lisa Arends, and those offering private info/workshops on how to pass exams (Tina and others). I have some files I send for free - see post up top, Passing the CPNE...".
Besides books, all one theoretically needs to pass all of EC exams including the CPNE is included in the cost of each exam. The only supplement to the stuff provided by EC I used (and got A's and B's and passed the CPNE first try) was the online practice exams through EC. THey also offer workshops and conferences at an extra cost. So do private companies. Whether you need to invest in them to pass or not, is up to you as a student.
One thing that really helped me study for the CPNE in addition to reading the CPNE study guide (provided by EC) 14 times to the point of memorization, is I found an online study buddy through allnurses. Or, actually, she found me! We emailed care plans
and it helped getting another's imput.
