Just to make clear you can do this on any platforms

Illusion-keep casting muffle any where you go
Conjuation-buy a horse of shadow mere and keep casting soul trap on him
Alteration-find a pond or lake and keep casting water breathing
Restoration-Join the collage of winter hold and on the last quest go to labarinthia, find the spell tome equilibrium in the first room on the table then cast fast healing and equilibrium very where you go You can also find telakaniss
Sneak-go to high horathgar and unequip all wepons/spells and Neal behing them and keep punching them
On/two handed and bow buy a horse or shadow mere and buy conjuring sword/battle axe/ bow and keep firing at the horse.
Smithing buy a ton of iron and leather strips and keep making iron indigots you can get theses also from the blacksmith glitch and the dawguard chest

Ps is I haven't done destruction or the rest of the skills because there's no fast way of leveling up that skill you just have to level them up naturally.

I meant Dawnstar as in the Town west of Winterhold. Also if you want to know where the dawnstar chest and the blacksmith chest glitch is just look it up on youtube

Or just play the game and let the levels come as you go. You don't have to powergame. Besides, those chest glitches don't work for pc players using the unofficial patches.

Not to mention that grinding Restoration with Equilibrium is totally counter-productive (Repel Undead on a group of draugr/skeletons is the fastest way to do it). Iron ingots are so last year too -dwarven bows are the way to go, followed by jewelry.

Speaking of the couple of merchant chests, not buried deep enough below the ground mesh... I'm guessing the whole fuss about them, comes from the early WoW days, when kids were begging for gold

But yes, grinding defeats half the purpose of spending your time in a role playing game. Just play and the levels will come.
