if u hav acess to the arch mages room in the arcane university make some spells that have magnitude 1, etc and go around casting them loads randomly. as they are so weak they will use hardly any magicka.
as long as u create spells in magic skills which u hav as ur main skills
these will contribute to your level growth, which will rocket as growth is measured in amount of spells cast, not how powerful they are or how much magicka they use.
kinda easy
