Law school is a grad school. You do have to apply to it separately. I’ve never heard of a law school in America that has a bachelor/JD program that some of the medical type grad schools have.

Say you go to Harvard. Harvard has an undergrad and a law school. Even if you were at the undergrad, you’d still have to apply to the law school just like anyone else who wanted to go there. Yes, they can reject you. Law schools don’t normally give any kind of preference to kids who went to the undergrad.

Best of luck

The general rule is that universities give advanced degrees, while colleges give only bachelor’s degrees or mostly bachelor’s degrees with a small number of master’s degrees. However, there are places that call themselves colleges for historical reasons that give graduate degrees (e.g. Dartmouth and Boston College) and there are places that call themselves universities that don’t give advanced degrees.

Colleges are usually smaller, but the two words are often used interchangeably.
