Nah, that's not how nWoD's basic rule system works. The system is insanely easy. The game only uses 10 sided dice. A roll of 8, 9, or 10 = a success. If you roll a 10, you get another free roll. If it is a 8, 9 or 10, it is a success (and if it is another 10, you get to.. guess what, roll again! ^^).
Basically, the more skill you have in something, the more dice you have. If you have 3 points of skill in a certain area, you get to roll 3 dice. Each point of skill = an extra dice to roll (increases your chances of a success). Depending on favorable/bad conditions, you might get an extra dice to roll, or one less to roll. If the action is against another person, more times then not the winner is whoever gets the most successful dice.
Pretty much, that is the whole game system, in a nutshell. It isn't really more complicated than that. Sure, it has it's nuances, but the system actually revolves around storytelling, rather than rules... which is why the kept the rules so simple, and the game can move so fast compared to D20.
