Yes, people find it one of the harder silvers. Frankly, if you understand it it gets easy (although it used to be really hard).
EDIT: To make my video I used QuickTime Player to do a screen recording. Then I watched while using QuickTime Player to do an audio recording. Finally I used shared the screen recording with iMovie and the audio recording to iTunes. From there you can combine the to in iMovie and share it to YouTube. Just make sure your video is a bit smaller than the YouTube screen. iMovie likes to randomly zoom in on whatever you've captured.
We made an expansion and it is awesome. Really, you should check it out, especially if you're looking for some extra challenge.
