Donald,
Video presentations offer the lowest "homework" requirement, as there is no one checking to see if you actually did any work or if you did what the quality of the work is. Likewise, they typically don't explain answers or allow you to ask questions in real time. So the effort there is pretty minimal: They check the "35 hours of PM Training Required" box to apply/sit for the PMP exam.
The bottom line here is, your exam results will indeed reflect the amount of effort you put into preparing for the exam. It sounds like you want a low-effort solution. Good luck with that. For me, studying for the PMP exam was like learning a foreign language.
I was once told by a mentor long ago, "If you want the goods, you have to pay the tariff." The tariff here is your time and treasure. If you don't put in the work, don't expect a good outcome.
