What questions should I ask?

When I visit the school what should I look for?

Now that I'm getting into fitness I want to start training in something again. I had done kickboxing for a year but it was a very mild school and I cant really say I was trained much for fighting... It was more fitness.

So now I would like to take Brazilian Jiu Jitsu as grappling was always my strength.

Any tips would be appreciated.
