I work for 1 of the 10 largest law firms in the entire world. This is what I can tell you about law school.
They only care about your GPA and LSAT. I know attorneys at my firm who went to smalls schools like Grove City College (and we are a liberal firm), and those who went Ivy League. It doesn’t really matter for the BA.
As far as which law school you go to: typically there are the following for primer firms (which honestly - not every attorney enjoys working at): 1) national law schools - which will allow you to practice anywhere in the country: the Ivys, Duke, Virginia, Michigan, Berkley, Georgetown, etc
the regional schools - which will get you into the local office of a premiere law firm: Villanova, Catholic University, Brooklyn Law, etc.
all the other accredited Law Schools which will still get you a BETTER job at a smaller firm if you graduate with good grades.
Regardless: the most important thing with LAW school is graduating top of your class from Law school because regardless of where you go, there are far too many attorneys graduating from law school then jobs avalible.
Regarding the MBA - a top MBA school is required if you want to be an executive at a big company and you want to avoid climbing the corporate ladder. But most MBA degrees count more after a few years of practical experience.
Now with that said, I know plenty of people who have good paying jobs after getting an MBA from schools like University of Delaware and Villanova. The most important things regarding the MBA is to make sure it is an AACSB accredited program.
