Your character must have a major skill of Sneak and either Destruction or Alteration. If your skills are Sneak and Destruction, gain access to the Arcane University. Go to the place to make spells. Make a Drain Health spell and make sure that it is set to "Self"and it only uses 1 Magicka. Then, go upstairs. Go into Sneak mode and just run into the wall without stopping. Activate magic repeatedly. You will soon gain levels quickly. Note: When you activate the magic it will seem as if it is hurting you, but it is not. If your skills are Sneak and Alteration, go into a room with a container (for example, cupboard, drawers, etc.). Run into the container in Sneak mode and use a "open very easy lock"repeatedly on the container.
