Better go to real money MTT. I was playing freerolls, but I thing micro cash MTT's will increase your skill.
You can play 0.5 or 1$ buy in ones, at the beginning, without playing scared money.
If you play tight, I don't think you can lose much, especially when you are playing in the weekends.
You feel great in freerolls because, I remember that, in the beginning most players are going all in with A2o or k9o and if you double or triple up. Then in the middle somebody calls your AK with A5o, every street, giving your 100BB
), and you are in the money. So, it's very easy, without any effort.
