As much as my name would not entitle me to marry the Queen or any other self respecting human being, my success in life does not depend on how bad my name is. Your question about a "Bad university" is analogous to the statement I began this response with.
You make the university and not the other way around unless you live in the US where pedigree is everything.
Many of the high achievers in life went to mediocre universities whilst some of the greatest failures, moron (George Bush Jnr at Yale, Michael Milken at Wharton, the entire Wall Street mess at Columbia, Harvard, Yale., Stanford, New York and Wharton).
Reputations are often about the good reputations. None of the above mentioned universityies boast George Bush Jnr, Fordham does not boast Bernie Madoff and so on and so forth. They only boast about their good ones. And these too are far and few.
So what university you choose is dependent on what outcomes you want in life.
