Education facilities

Should I build my education facilities as much as I need or more? What level of index should I aim for, I have tons of trillions of money.

Depending on pop size...index of 160 - 180 ish should do you, don't over cook it. Always keep the 3 different school type indexes the same.

Thanks Crafty

I have a better idea: send me some of those tons of trillions of money ;)
