Well, nothing else to say, just look at the title .
Btw. I do consider the different factors such as the enemies school and level, so I am a level 36 Balance wizard who is currently in Mooshu and Wysteria :D
I completed Wysteria in a day as a Level 25 Wizard. (I did all the side quests and leveled up about five times). It was very easy and I was able to solo through all of it. The final boss, Randolf Spellshine, is very weak and doesn't seem as bad as people described him to be. (I was able to take him out in two hits using a Feint, Life Trap, and a tough enchanted Seraph). Your level seems a little too high to do Wysteria, so it would probably take you shorter than me to finish it. I finished it (including the side quests) in about half a day.
