Quote from @Robert Gunn: I would also be very interested in hearing student or JV experiences with Pete and his program.I stumbled upon him by chance and for fun (I've been investing in land for years) signed up for his "free" course, which he promises after he pitches his $499/mo software system (which is basically an overpriced CRM) and then after the first "Level" in the course, you are directed to a pay page to access the rest of the "free" course.
