The Olympics on NBC are great programming for practicing scales. Between all the stories and ads, there's plenty of content to ignore.
I've had my eye on the websites for SDSU and CSUN jazz programs since deferring enrollment at LAMA. They have lists of required repertoire and scales. I found my skills moderately deficient in most of the scales listed for SDSU's program, so I've been running them in all positions and keys during the Olympics for past couple weeks. There are even a few weird ones I'd never heard of like Harmonic Major and Oriental Dominant Mode.
