Law / Driving Licence in Warsaw - how many times? (foreigners) [3]

Hi guys (and gals),

I have been looking for information about passing the driving test in Warsaw, but with little success.
I am currently enrolled with Imola, and all the formalities are clear and simple.

But has any of you here actually past the driving test in Warsaw? How many tries? Are they more strict with foreigners? I read polish people pass easy (lucky ones) or after a very long time (11-13 tries in extreme cases).

Cheers!
