One of the five Columbia students busted for alleged drug-dealing in frat houses and dorms not only plans on returning to the Ivy League campus once he makes bail — he also wants to go to law school.

“Going to Columbia was my dream, and I plan to finish,” said Chris Coles, 20, in an interview at the Manhattan House of Detention, a day after the arrests rocked the university.

Coles, an anthropology/political-science major who allegedly sold $5,000 worth of pot to an undercover cop to finance his tuition, said he wants to attend California-Berkeley’s exclusive Boalt Hall Law School after graduation.
