Okay, I want to create a Mystic Theurge in 3.5, going Cleric/Wizard 3/3. I would start with 3 levels of Cleric and then do 3 levels of Wizard. On the Wizard side I also want to be a Wizard with School Specialization.
In the School Specialist description it says
The wizard must choose whether to specialize and, if she does so, choose her specialty at 1st level. At this time, she must also give up two other schools of magic…
Does this mean as a 1st level character I must choose the school, or when I take my first level of Wizard I must choose the school?
