MySQL for Administrators course from Oracle: worth it?
I previously taught that class.

It's not the worst one Oracle offers, that would be the Performance Tuning course (which I hear was recently refreshed, so maybe it is better).

It depends a lot on your learning style, but you will never learn as much through a CD or internet based training as you will with having the right instructor in front of you who can answer all your questions, and challenge you.

There's not 5 days worth of material in it, since now on the last day they do the DBA exam.  You may also spend the first half of day 1 being marketed to if your instructor follows the schedule (some just exercise civil disobedience and skip the garbage).

You may also find it disturbing the over-focus on things like stored-procedures.  That's more marketing, because MySQL is trying to make sure everyone knows they have them.
