A few people stated that by working as a lawyer I wasn't necessarily going to be dealing with the constitution and law school is probably not what I think it is. Can anyone give me some more insight on what to expect?
What they mean is that the vast majority of lawyers do not practice Constitutional law. Constitutional cases, which would include things like civil rights, free speech, voting rights, etc., make up a VERY small percentage of all the cases filed. The people who do handle these cases tend to be highly experienced specialists.
The majority of lawyers deal with more mundane things like contract disputes, wills, divorces, and DUIs.
In law school you will take one required Constitutional law class, and have the option to take a few electives that also deal with Constitutional issues. You don't major in law school like you do in undergrad, you just take a lot of required courses and a few electives. Most of your time will be spent taking required courses like Contracts, Torts, Property, and Corporations. Most of it is very dry and difficult (especially the first year).
