MySQL training

[cross posted to mysql]
  I keep getting the MySQL AB emails about training coming to my town, but never go.  I'd like to formalize my knowledge with the MySQL but at the sametime I've got a pretty bad impression of almost all certification and training courses, and the one provided by AB seems like a top gun program ( 5 days to learn how to be a Admin) which makes me wonder if it will be effective.   Anyone here actually ever taken one of their courses?
