the education is excellent, for a beginner or for someone with some knowledge. you get a lot of knowledge from the ground up.
as to your other questions, greg jensen is OA head and he does have a fund with investors. you'd have to ask what his returns are if you're interested, that I can't answer.
the instructors do real trades, with real $$ and they post them real time (both the trade and adjustments). a very, very large percentage are winners, i can verify that. the issue is this: trades done are not a lot of contracts. therefore, the adjustments are sometimes are buying 100 shares to save a 1 contract put spread. theoretically correct, and the trade usually becomes profitable in a month or 2 or 6. however, if you sold 10 or 20 short puts, would you buy 1000 or 2000 shares, potentially holding them for a long time, tieing up so much capital to "save" the trade? doubtful, you close a bad trade or let it expire and hunt for new set-ups. that's reality.
