As a Project Manager, I’ve learned in various ways: practical work experience, books, insights and guidance from other Project Managers, blog posts. One important way of improving my PM knowledge and skills is finding and taking exceptional online courses.
I want to share with you the ones that helped me the most.
Joseph Phillips has a few very good PMI Exam Prep courses on Udemy. This is the PMP Exam Prep:
