I FC'd School's out on Easy and i wasnt trying at all...
But for some odd reason i cant FC Slow Ride on Easy...
I'm sick of that song......
(U may laugh at the fact that im doing it on Easy)
The order of the songs isn't exactly good in terms of difficulty progression; I found most songs in Set 1 harder than the stuff in 2 and 3 on both Medium and Hard.
Also, note that FCs (or progressing to post-Medium difficulties) don't happen overnight--they require a crapload of practice.
