They will even book chefs or yoga instructors if needed. 

Ben is an awesome instructor.

I have a natural knack for programming, and started realizing that I was better at it than my instructors.

Call your old real estate school instructor and ask him.I notice that you are figuring out that listing is more lucrative that working with buyers.

Even the latest changes, which was the main reason to take those Courses, seemed to baffle the in-person Instructors.

Four and a half days of classroom with an amazing instructor learning everything from time value of money , to valuations, to cap rates, to internal rate of returns.

Regarding mentors, don't expect them to work with you for nothing, their time is valuable and their pain and sweat has gotten them where they are now, an instructor once told me, "there is no such thing as a free lunch" so expect to trade something with them, time, money, grunt work, something.

I have a BS in Exercise Physiology and certifications through the American College of Sports Medicine (ACSM) as an Exercise Physiologist as well as Group Exercise Instructor.

They are great and worth every penny.Even if a class isn't real estate specific, you can always approach the instructor afterwards and tell them you're having trouble applying the techniques learned in class to your real estate investment analysis.

Way easier if you have a RE background, think I did the 80 hour course in a weekend.Don't have much advice for classes, I started to take it live 10 years ago thinking it'd be better and the instructor pissed me off so bad at the nonsense he was teaching I left without finishing.
