1. PMBOK - Project Management Body of Knowledge

This is an excellent reference to use while studying for your PMP exam and throughout your career as a project manager. It's a must-have for any PM!

2. Agile Practice Book

This is a high-level overview of the agile project management method. This is important to know since many companies have transitioned away from traditional waterfall methods to a more iterative, agile method.

3. Rita Mulcahy's PMP Exam Prep

This was my top resource when studying for my PMP exam. It's extremely comprehensive and provides excellent practice questions to test your knowledge.

4. Project Management Academy's Online Study Materials

The big reason why I took my prep course through PMA is because of all of the study materials they provide. My favorite one is the mock exam which will allow you to simulate what a test might be like.

5. Effective Project Management by Robert Wysocki

This is a fantastic book that gives you a much better idea of what being a PMP is actually like in real life. It provides a different perspective on how to think like a PM.
