I've booked myself into two courses at Big Nerd Ranch (Atlanta). I've booked the Objective-C and Cocoa course in January and the iPhone Bootcamp course in February. I'm hoping I can cancel the January course if I learn quickly enough, but expect i'll go on the iPhone one regardless. Has anyone been on any courses at the ranch before? What kind of standard / activities / hands on work is there? Any comments are appreciated, Thanks.
