Make your character a Dark Elf with the birthsign Warrior, and create a class with the following attributes: Athletics, Acrobatics, Blade, Block, Blunt, Heavy Armor, and Marksman. Next complete the arena to get leveled up. Then, get a horse and go to the lady in Kvatch. Note: You may have to shut the Oblivion Gate. Once on your horse, talk to the Orc woman at Kvatch and sell your most expensive equipped weapon until you have 55,000 gold. Then, join the Fighters Guild and complete your first mission. Then, go directly south of Imperial City and find a bridge. Cross the bridge to find a place called Vindisel. Kill a lady named Umbra and take her armor, shield, and blade. Next, go to Imperial City and mess with the guards. Every now and then when you are about to die, run from Imperial City before the guards kill you, or pay the fine using the gold from Kvatch. After you level up, go to any Fighters Guild and train your major skills. Then, attack the Imperial Guards and repeat.
Use the following trick for easy experience in Leyawiin (Blade, Blunt, Hand to Hand, Destruction, Marksman and Sneak). Go to Leyawiin find Rosentia Gallenus' House. She has four Scamps. You can kill them and more will respawn. Sneak attack with a blade, mace, or hand to hand. Then, use a bow and cast fire. Note: If you use your bow, the arrows are hard to get back. Note: If you finish the quest you cannot do this anymore.
Go to Cloud Ruler Temple northwest of Bruma. Walk up the big stairs. You will see two Blades sparing. Stand close to them for a minute and your Blade and Block skills will increase by 2. Note: This can only be done once.
Use one of the "Easy money" hints and get at least 500,000 gold. Then find a place (taverns recommended) with two trainers who train in any two of your major skills. Train with one of them until you cannot do so anymore. Then, train with the second one until you cannot anymore. By now you should get the level up icon. Go to sleep and level up. You can repeat the process until you reach maximum level or max out the two skills.
You must have Conjuration as a major skill. You will also need Blade, Blunt or Marksman. Summon a monster such as a Scamp or Skeleton. Kill it with your weapon or shoot it with arrows. Repeat this for a few minutes and you will get the message to level up. This may take longer if you already are at a higher level.
