I'd like to respond to this, as I find Blanch's response annoying.
I give students the information, how it's used, and will even play it over music. After I leave, it's up to YOU to follow through. I ain't gonna call you every other day to make sure you're putting in the time.
And let's face it, with YouTube being what it is, you don't even really NEED private lessons anymore, just a bit of self discipline and a metronome. Guthrie Govan is self taught, what's our excuse?
If I were assessing students the way I'm being assessed, I'd say most are in it for the wrong reasons, they don't practice what they've been showed, etc.
To put it in terms everyone can understand; it's all about time and being realistic. If you put hours into your playing, it'll show. If you'd rather play video games and get drunk and get laid and guitar's more of a fun thing, that's cool too. But don't expect a certain level of playing to just jump out of you. Don't expect to play huge sweep arpeggios when you can't even nail pentatonic boxes. A lot of dudes want to walk before they can run, and that's fine, but don't blame the teacher.
Here is my teaching style, I don't see how I can make my explanation any more simple than what it is there.

As for Mark Evans, I believe he's teaching out at 5 Star Music and Dean Wells is still in the St Kilda (Kooyong area). Both guys rule.
Thanks for your time.
