Product Notes
Rita Mulcahy's PMP Exam Prep: Rita's Course in a Book for Passing the PMP Exam

This 7th edition trade paperback is the lowest-priced PMP guide in the group. It's in good condition and carries the familiar Rita Mulcahy title for PMP test-takers. If you're looking for a no-frills study book to read and mark up, this one fits. The limitation is the edition: it's older than the 8th edition offered elsewhere in this comparison, and the condition is not like-new. The low price makes it a reasonable entry for budget-conscious candidates.
PMP Exam Prep : Rita's Course in a Book for Passing the PMP Exam by Rita Mulcahy

This copy is noted as the 6th edition aligned with PMBOK Guide 4th edition. It's in good condition and has no writing, no highlighting, and no notes inside, which is useful if you want a fresh interior. The trade-off is the edition: it's the oldest PMP edition in this set, even though the price is mid-range among the three PMP guides. If you prefer a clean copy and don't need the newest edition, this is a sensible pick.
PMP Exam Prep, Eighth Edition - Updated: Rita's Course in a Book for Passing the

The 8th edition is the most recent PMP edition in this comparison, and this copy is in like-new condition. It's a revised trade paperback published in 2013, with 624 pages of content. The reason to choose it is the combination of a newer edition and a clean, unmarked condition. The limitation is that the title is truncated-it ends at "Passing the"-so the full subtitle is not visible. Also, its price is the highest among the three PMP guides.
PERSONAL TRAINER CERTIFICATION EXAM PREP COURSE (2ND By Katie Donnelly BRAND NEW

This is the only personal trainer certification product in the group, and it's brand new. The title states it's the 2nd edition and highlights over 750 practice questions to help you pass your personal trainer exam. If your exam goal is personal training, this is the direct match. The limitation is that it's the most expensive item in this comparison, and it offers nothing for PMP candidates. The trade paperback format is brand new, so you're getting an unread copy.
Final Recommendation
If you're taking the PMP exam, the best fit depends on how much you want to spend and how current the edition should be. The 7th edition Rita Mulcahy PMP Exam Prep is the lowest-priced option. The 8th edition, also by Rita Mulcahy, is the newest PMP edition and is in like-new condition. The 6th edition sits in between, with a clean interior noted. If you're preparing for a personal trainer certification, the Katie Donnelly course is the only item tailored to that exam and is brand new. Choose based on your exam target and your preferred edition, and you'll have a suitable prep book.
