Some advice regarding schools,
in my experience, out of the starting provinces, the following regions are suitable for school/universities
Anatolia: it has so many cities un-spawned that it can support 2 schools
Mesopotamia
Rumelia
Egypt
egypt requires effort to spawn the last couple of buildings,
build a major fishing port here, and upgrade to the very last farm,
and they all require madrassas on all other cities,
which has the positive side effect of spawning needed priests
