"He goes to two universities."
Translation:Él va a dos universidades.
I agree, when speaking about attending a school, you need to pay attention to the idiomatic usage of "go" in English, meaning "to attend". In Spanish, you would want to use the verb "asistir" if you are intending to mean that a person is a student at a school.
"asistir" means "to attend" and thus saying "él asiste a" is the same meaning as saying "él va a"
