Full disclosure - I am biased towards the PM PrepCast's training material - which I used to pass my exams (PMP and PMI-ACP).
I also prepped for and passed the PMI-ACP exam while navigating a divestiture (that I was project-managing) and the hours were intense (12 hours on average).
This was also when my child was just 2 years old, and needed a good amount of attention and care from me!
The flexibility offered by PrepCast was immense - listen to lessons on my commute, lessons on demand, etc.
Of course, above all, I believe in practice - so I kept practicing in bite-sized portions (often I didn't have time for a full test).
I strongly believe in the power of breaking things down.
As a previous mentor used to say "How do you eat an elephant? Cut it into tiny pieces, that's how!"
