Choosing an exam certification prep book starts with the exam you're targeting, then comes down to how much prior use you can live with. This set includes three Family Nurse Practitioner review guides and one Linux+ guide, so the subject-area decision is clear before you even look at price. Once you know your exam, the remaining choice is about condition, format, and how much you want to spend.
Quick Take
All three FNP options are versions of the same Family Nurse Practitioner Certification Intensive Review title by Maria T. Codina Leik. The Linux+ Guide to Linux Certification by Jason Eckert is the only title for a different credential, and it is the outlier here in subject and price. The FNP titles differ mainly in condition and listed price, so your exam choice narrows the field before price matters.

Product Notes
Family Nurse Practitioner Certification Intensive Review, 4E PB (ACCEPTABLE)

This $24.00 FNP review book is the middle-priced nursing option, and its selling point is physical sturdiness: the binding is tight, the spine has no creases, and there are no loose pages. That matters if you plan to flip through it repeatedly while studying. The trade-off is that the pages show signs of prior use, including notes, underlining, and completed exercises, and the covers and edges have moderate wear. Because it is an acceptable-condition copy, you should expect a working study aid rather than a pristine reference. If you are comfortable with used markings and want an FNP intensive review that can survive some handling, this one gives you a solid text at a midrange price.
Family Nurse Practitioner Certification Intensive Review 4th Edition

At $20.99, this is the least expensive FNP certification review in the group. It covers the same review material as the other two nursing titles and is aimed at adult and professional learners, so the reading level fits someone preparing for advanced certification. The catch is that the book is both highlighted and written in: tests throughout have been answered, and the online code from the previous owner has been used, so its reuse is uncertain. If you mainly need the core content and are willing to ignore prior markings, this price makes it an easy entry point. If you want to answer the practice tests yourself, you may find this copy less useful because the answers are already in the book.
Family Nurse Practitioner - Paperback (Very Good)

The most expensive FNP choice here also shows the least prior use. At $32.74, this Very Good trade paperback includes interactive digital prep and robust study tools. It has all pages, legible text, and only minor wear or possible light markings. For someone who wants a cleaner working copy and is willing to spend more than the other two FNP books, this is the most comfortable option. The limitation is simply the higher price. If you want the least-used nursing review in this set, this is the one to choose.
Linux+ Guide to Linux Certification

This is the only title here for Linux certification, and at $6.71 it is also the least expensive book in the comparison. The Very Good copy shows normal use and light wear, with possible light notes or markings, but it remains a solid, nice reading copy. Jason Eckert's Linux+ Guide covers Linux+ exam prep in a trade paperback format. If your goal is the Linux+ credential rather than a nursing certification, this is a low-cost way to get a full study guide. The limitation is that it does not help FNP candidates at all; you would be buying it for a completely different exam.
Final Recommendation by Use Case
If you're studying for the Family Nurse Practitioner exam and want to keep costs down, the Family Nurse Practitioner Certification Intensive Review 4th Edition is the most practical starting point. If you need a copy that will sit open on a desk or get tossed in a bag, the Family Nurse Practitioner Certification Intensive Review, 4E PB is built for handling. If condition matters more than price, the Family Nurse Practitioner - Paperback (Very Good) is the cleaner pick. For Linux+ candidates, the Linux+ Guide to Linux Certification is the straightforward low-cost match.
