Free money

I just signed up to pokerstrategy.com who give you free money if you pass a quiz on no limit texas holdem.
Yes that's right, free money. I'm sure the catch will become apparent in time. I just moved house so the only poker I've played lately was a steep blind-structure sit and go with my buddies which I luckboxed my way to victory in, and a little fun cash game with the same dudes. I am developing the ability to assess flops a little better than I used to and to quickly observe player traits and likely hand ranges, which is improving my post flop game. I've just got back online in the new pad and things are still the same playing cash: I am a little too passive, and not quite ready for multitabling as i have a leaky preflop game. I am starting to think that what I need in poker is some like minded friends to 'sweat session' with and to haul my ass to some live tournements.
