It looked like (and sounded like) he left the engine with some power still on as he touched down. I think if he had switched off the engine upon touchdown the aircraft wouldn't have bounced around so much as it did.
Good landing though.

I remember when I was at that level of training, 5 hours of PIC was great! I wonder if he had to pay for it!
What I find curious is why it veered to the left. It should have veered to the right. Looking at the nose-wheel, he was steering to the right. The only thing I can think of, is that he was applying a bootful of brake, (and why would he?), and with only one brake ....

He probably applied full left-braking to compensate for what he thought would be a sharp pull to the right upon the right wing making contact with the runway. Apparently the pull was nowhere near what he anticipated.

Because as soon as the left main contacts there is a lot of friction on the Left Main and Zero Friction on the Right side. The rotation appears to accelerate as the airplane slows down because of the loss of rudder effectiveness as the airplane loses airspeed. Couple that with the fact that he has close full Left Aileron in to keep the right wing off the ground and the airplane goes Left.

Quoting longhauler (Reply 10): From the brake. Unless the wheel were damaged or there was bearing friction, there would have been little other drag.
The aerodynamic drag would have been virtually nil by the time the aircraft veered, as it only veered during its last few seconds of roll, and speed looked to be less than about 20 knots by that time.
After watching the video again, I think it is very plausible that he touched the brake at the end. I would expect him to go left holding the wing off as long as he did whether or not he touched the brake. There is friction from the wheel that is increasing as the wheel rotation decreases. How much isn't as important as the fact that there is a difference in drag between the left and the right. The nosewheel is probably skiding and not providing any turning force whatsoever. The rudder being held full right to counteract the full left aileron is losing effectiveness adding to the nose left tendency. If it were JUST this though, I would expect to be a more linear/gradual process than what is seen at the end of the video. So probably he touched the brake.
