A private university (Ivy, etc.) costs $50,000 a year (roughly). UC-Berkeley or UC-San Diego cost with housing $35,000 a year (my friends who have kids there are paying that), but you many graduate in 5-6 years because not every class is offered every year due to budget cuts, etc.
So 4 years x $50,000 = $200,000.
5 years x $35,000 = $175,000.
6 years at $35,000 = $210,000.
