Starting the Journey

I finally took the first step.

I've been stuck in middle-of-the-pack IT work for the last 5 years. I don't have the technical expertise to transition to a full-blown engineering role, but I have the people skills to sit in a lot of those meetings. The people and project management side of my work has always been what I loved, and I snapped and decided I can't change passwords for one more day.

I bought DM's Udemy course today, and am beginning work in the evenings. Wish me luck!

The question:
-What should I expect to prep here? Do I just do the whole course, take his practice exam, then sign up for the PMP exam?

-Is there other stuff I should do between the course and the test?

Thanks in advance!
