I don't believe they've done tech classes for at least 6-7 years. I attended one in 2004 or 2005. Truthfully, you'll never learn as much in a training class lasting 1-3 hours as you will just working on markers and iterating trying to solve problems. I attended the class but got to understand them by working on them at Pevs. And working on more of them. And then more. And then more.
