How many quests in Oblivion\'s (The Elder Scrolls 4: Oblivion)

I don't know what to do in this game:
1. Passed the main story quest
2. Passed the fighters Guild
3. Passed the thieves Guild
4. Passed the assassin's Guild
5. Passed a lot of normal quests with taverns
6. Passed The Arena
And in General I got 134 of the quest (I'm level 14)
P. S. I failed the mages Guild and they kicked me
