@YunSyed Utter nonsense, unless we’re referring to the graduate level rather than undergrad, and even then that’s discipline dependent.
Let’s look at the [NRC’s rankings](NRC Rankings in Geosciences) of geology programs. Though these are still fraught with problems, the NRC is somewhat respected and it’s about as good a ranking as one would get. According to your definition the geology program at the University of Colorado - Boulder is third tier. Should you tell any real geologist this, they would probably respond with an askew look and telling you that you have no idea what you’re talking about. Especially for most undergraduate work, save for the few subdisciplines it lacks, Boulder is a first rate school with outstanding opportunities for field work. A true third tier school in geology would only offer a few courses to service the gen ed needs of the student body, lack funding for field work, and not have professors involved in researching various questions.
Generally speaking, if a program is ranked, it’s not a third tier one.
