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.

I passed!!! —Highly Recommend
Format: Paperback
Great study guide and structure tailored to the 4 domains that are in the CAPM Exam. I just passed the exam on my first try scoring above target in 3/4 categories and target in 1/4 categories. The online simulations was a great way to prepare for the exam. Highly recommend you purchase to pass the first try! (This and the PMBOK Guide 7th edition were the only study materials I used)
