Not sure if it works, but I found this:
I was playing Skyrim last night and i found a glitch that can help you level up at the beginning of the game. When the beginning scene is finished you'll follow and Imperial to a small fort where you can continue to follow the Imperial or a Stormcloak (you can follow either for this to work). Whom ever you chose to follow will give you a small tutorial of the game as you escape the turmoil created in the beginning scene. As you go through the tutorial you will come to an under ground cave where you'll be taught how to perform sneak attacks. At this point you'll be asked to either sneak attack a bear or sneak past it. Instead of doing either of these you can enter sneak mode and go behind which ever NPC is giving you the tutorial and attack him over and over again with no consequence since he will not retaliate or die. You can use this to level up your one-handed, sneak, two-handed, and destruction skills. I'ts better to get them into a corner because when you hit him he will be pushed forward. This is very useful if your willing to put the time into it, I used this to only level up my sneak to 100 and ended up leaving the cave around lvl.18.
