Made Med-Surg Less Overwhelming
Format: Kindle
This book broke down complicated nursing topics in a way that actually felt manageable. The practice questions and real-world examples helped me feel more confident and less anxious while studying for exams.

Chaotic Table of Contents, Chapters and pages in TOC are incorrect
Format: Paperback
I just opened it and the Table of Contents is "Chaos." The Chapters and pages in the Table of Contents (TOC) do not reflect the actual chapters and pages in the book. For example, TOC shows Chapter 8 in page 94. But if you turn to page 94, it is the second page of Chapter 9. Will continue to update this review when I start to read the book. For now, it is a "1" for the Table of Contents.
