I thought the celta in Baden was awful - a real downer instead of an enabler.
Was this TLC sprachschule? What did you think of them? I am planning to go there to do the DELTA module one later this year. It's about 10x the price of doing it online, is it a good center?
I'm use to taking (and giving) technical courses and wasn't impressed with standard of expertice there. One course colleague was planning to leave she was so p***ed off and was given tutor advice to smile more when teaching. That's about the level. I had hoped for help with coping with real-life teaching not perfect lessons that take hours to prepare but I guess that's aproblem with celta the world over.
