Making it real

I started the mastering program at PUC-CAMP this weekend (friday's night and saturday's morning) and I'm pretty excited doing it.
My first sight was kindly strange when meeting my fellows. All them have more market experience then me, some as telecom professional, as market sales, teacher and others. I also get interesting about the content: I found some areas of interests to me: in practice the top layers in OSI model (application/services).
