PokerStrategy provides you with a $50 starting capital if you pass their quiz. They supply all the information you need to pass on their size so it's an easy quiz if you simply look up the answers. The $50 counts as "bonus cash" so while you can play with them at real money tables you cannot withdraw them, unless you generate enough bonus points from rake.

One thing which I dislike about Poker though is that the feedback is NOT immediate. If you want to know how good you play you either have to save your hand history and perform many complicated calculations between games, or observe how your balance changes over a long time frame.
