Before you commit to exam certification prep, figure out which exam is actually on the calendar. This group of study guides covers three different credentials: Linux+, Family Nurse Practitioner, and CSET English. The listed prices span $6.71 to $32.74, so the decision is not just about cost; it is about matching the book to the test and to the way you study.
Quick Take
If Linux+ is the target, two copies of the Linux+ Guide to Linux Certification are in the mix, with the lower-priced copy giving you the same core text for less. If the Family Nurse Practitioner exam is the goal, the Family Nurse Practitioner Certification Intensive Review, Fourth Edition is the nursing-specific guide here. For CSET English Subtests I-IV, the CSET English Book + Online guide adds an online study component to the printed material.

Product Notes
Linux+ Guide to Linux Certification (Test Preparation) - Lower-Priced Copy

This copy of Jason Eckert's Linux+ Guide is the lower-priced way into the same content that appears in the other Linux+ guide. It has ISBN 9781418837211, the same ISBN as the higher-priced copy, so you are getting the same textbook without paying extra. The used condition means you should expect normal wear and light markings from a prior reader. That is also the limitation: this is a working copy, not a pristine new book. If you care more about the study material than the condition of the cover, this is the sensible call.
Linux+ Guide to Linux Certification (Test Preparation) - VERY GOOD Title Copy

If you want the condition stated directly in the product title, this copy says VERY GOOD and costs slightly more than the other Linux+ guide. The certification content matches the other Linux+ guide, so you can use it side by side with practice tests. The limitation is that textbooks may not include supplemental items such as CDs or access codes, so this is a book-only purchase. For someone who already has a practice-test platform and just needs the Linux+ material, that limitation is easy to live with.
Family Nurse Practitioner Certification Intensive Review, Fourth Edition

This is the guide to reach for if the Family Nurse Practitioner certification is your target. It is a New Edition from Maria T. Codina Leik, and it includes interactive digital prep and robust study tools, so there is more than a printed page to work with. The package is the most expensive option in this group, and that is worth accepting only when FNP-specific coverage is the priority. The limitation is the used condition: the copy may show slight markings or highlighting. You are getting a complete review book, but it will look like a book that has been studied from.
CSET English Subtests I-IV Book + Online 2019 Teacher Certification Test Prep

The CSET English guide by John Allen is the book-plus-online option in this set. The title includes 2019 Teacher Certification Test Prep, and it is a Revised edition, which matters if you want study material that has been updated. It is in VG condition, so the pages are intact and there are no tears or marks, but the used-book wear is still present. That visible wear is the main limitation if you want a fresh copy for your desk. The bigger strength is the combination of printed content and online practice, giving you two ways to move through the CSET English material.
Final Recommendation by Use Case
- Linux+ on a budget: Choose the lower-priced Linux+ Guide.
- Linux+ when you want condition stated in the title: Choose the Linux+ Guide copy with the condition phrase in the title.
- CSET English: Choose the CSET English Subtests I-IV Book + Online.
- Family Nurse Practitioner: Choose the Family Nurse Practitioner Certification Intensive Review, Fourth Edition.
