It's the one where you have to jump over gaps, right? It's intended to be hard. I remember getting to hole six somehow, and I got 14 or something levels from that training (failed everything else for some reason)
You get most of the levels from the one, where you have to jump over gaps. Try practicing that one! Skip the rock thing, and for the tricks one, don't wear hats, because they make it harder to do flips.
