Seriously? Player.setlevel xx (where xx defines a number). There you go. Easy as that. If there's a skill you want to level, go with "player.setav skillname xx" or "player.advskill skillname yy" (where xx defines the skill level you want with the setav command and yy defines the xp points you want in the advskill command).
Saves you from having to grind. Unless you play on a console, then you can't use console commands - on a console. Go figure.
