Are these rankings too good to be true?

I think the rankings of some of the colleges I’m considering are too good to be true and want to know other opinions on this. I’m a HS senior and don’t know if I should be taking the US Newsweek rankings with a grain of salt or not. I’m planning on majoring in finance and possibly accounting and here are some examples of what I’m talking about…

U of Scranton- 16th in Finance and 20th in Accounting
Marquette- 15th in Finance
Xavier- 22nd in Finance
Saint Joseph’s University- 10th in Accounting

They’re all decent schools but by no stretch are they Ivies. For example I don’t believe that Scranton has a better finance program than Cornell. Do these rankings even somewhat reflect the program of the school?

Ranking is often done in a naive fashion. The four examples mentioned reflect that danger.

I would not put much value on these or any ratings. And I certainly agree that Cornell should be ahead of UScranton in any ranking (and I did visit and like UScranton)
