Helped Me Pass the CAPM
Format: Paperback
You need more than this to pass the exam, but this is an excellent study guide and structure. The practice questions are way easier than the actual exam. Don't let them give you a sense of false confidence. Especially if you don't have experience. I recommend to Google project management courses, IBM, or there's another one on Udemy. Use the PMI practice exam, too.

Typos and confusing/missing information
Format: Paperback, Format: Paperback
I finished Domain 1 and it's okay. Things are explained well, but there are a lot of typos and strange formatting. The cover of the book says 2025-2026, but the spine of the book says 2024-2025.
The way that the quiz questions are worded is confusing and sometimes repetitive. I had 2 of the same questions in a row in one section. I'm struggling to take some quizzes because the questions that are being asked do not reference any material from that section (or anywhere in the book so far). I feel like there is information missing in the sections because the quizzes have random terms that have never been mentioned.
Example: D1: Essential knowledge questions
I am being asked about estimation tools like story points, relative estimation, and planning poker. Nowhere in the book have those things been mentioned.
