It might be more difficult to get the melody to sound properly in the 3rd movement....
Technically it sure looks more difficult than the first two movements, but with good fingerings you can probably play it (if you can play the first two). But it might take up a lot more practice time than the first two movements, so If I were you I would start looking at it. =)
(I did this completely wrong myself. Worked my way through the 1st, 2nd, and then started on the third.. which isn't the ideal way if you have limited time.. me stupid

)
Oh well, the fingerings for the third has already been slightly discussed. (see post above), but try to make your own before looking at the other's. Maybe you find that your own way is more comfortable with you. I didn't, but you never know:P
Anyway, it shouldn't be that hard to get up to speed. That of course depends on your level, but I find it at least easier to sight-read than the two first movements. (no, not in proper speed

)
Anyway, good luck!
I'm not finished with it yet myself...
If I ever manage to play it good enough, I'll post a recording

It would be nice if you(and others) could too, (when you are finished that is, no pressure

) so that we could compare each others recordings+++ I think that could be nice...
Bye for now! =)
Best regards,
Joachim
Edit: You will probably figure it out yourself, but the third movement, is VERY fun to play
And btw, this goes for all three movements, I don't know if you are or not, but just a general tip that I've heard from others as well: Be loose in your wrist
