what are some fast ways to level up?

5-10 reasonsare good enough

ummm... increase your major skills?

That question is a little vague. I always choose Alch as a Major skill. You can raise it rather fast to level. Skills like Marksman, take a long time. I always pay a trainer for those. If your asking about ways to increase a given skill, try the wiki for training tips.

EDIT: I would be careful about leveling too fast. You could get behind in the enemy to player scale. This could make the game very very hard.

i just get conjuration. u can level up that skill by just summoning stuff

Here a few ways (assuming they are major skills):

- Conjuration: Repeatedly cast bound dagger while holding the block key, and quickly sheath the dagger. If you do it right, you can cast several times very quickly.

- Sneak: just sneak inside a castle where there are guards around, point at a wall, use auto-walk and go get a snack. Easiest skill increase method.

- Alchemy: Buy out all of the ingredient stores and taverns and start mixing.

- Speechcraft: not really fast, but easy. When persuading someone, just select the two dislikes with the big wedges. Even though their disposition is 0, you can continue to do game after game.

- Security: Requires Thieves Den. Use the training chest.

Go to Edgars Discount Spells in the Market District and buy the basic spells and then keep casting them-Try to keep near a 9/10 full magicka bar because it seems to regenerate faster.Don`t increase any skill by more than 10 in any level because collectively increasing by 10,skills related to an attribute skill maxes the attribute bonuses to 5 and anything more is a waste-and will make the game harder.
I try to max Willpower 1st -alteration -faster spellcasting.I believe strength and intelligence slow levelling by making fights shorter,and hits fewer.
I often visit Abandoned Mine just outside Skingrad on the Anvil road to boost my armor skills-There`s lots of archers there who you can melee fight and can`t do much damage,but every hit boosts your skills fast-I can exit several levels higher on light armor/heavy armor,block and armorer.Hitting these guys with a weak weapon or hands also means fights last longer and boosts blade/blunt hand-to-hand skills fast.
Try to earn money fast so you can be trained every level-Alchemy brings money and Ayleid ruins-If you want to max other skills fast then Honditar and Northern Goods in Chorrol,Pinarus in Anvil,Gruiand in Cheydinhal chapel,Mandil in the IC,are good for some of the hardest skills Athletics,Mercantile,Marksman, Speechcraft and Lockpicking.
Visit Shady Sam outside the wall N of the W entrance to the IC to buy lockpicks at every opportunity.
Try to find as many flax seeds as possible (Skingrad) for faster spellcasting.
If you want to level fast,pick from alchemy,alteration,mysticism,illusion,conjuration,L/H armor,block for Major Skills-Best not to though because your character may become too weak.
-That`s the way I`ve maxed out the last few times anyway.
