You need to always know the size of the pot and what pot odds you are getting when you need to make a decision. You could go to some online site and watch the quickest game you can find, keep track of the pot size and the odds each player has when they make a decision.

I believe that someone posted some outs problems a month or two ago. Can't remember if it was here or RPG. Or you could try just dealing out three and two cards and seeing how quickly you can work out the chance to improve. In fact that would be quite a good computer program to knock up. Flash a couple of hundred flops in front of you give your self a second or two to get the outs/odds needed and see what score you get. Repeat until you feel you don't need to improve.
