My daughter just graduated with a double major in Journalism and Communications from UMASS and is going to NUSL in a few weeks. I don’t think it made a difference what she majored in. However, I always let her know that making a really good living in Journalism and Communications would never be easy, but that if her plans were law school, then to study in an area where she had passion. Maybe you don’t consider Northeastern to be a satisfactory level law school for you, but I doubt it will close any doors for her and I don’t think her major kept her out of the top law schools. As others have written, those LSAT scores provide that separation.
Law School does seem like more of an afterthought to you, but you should put some focus on the LSAT. That requires dozens of hours of prep. Take practice LSATs and see where you stand. You’ll actually have a fairly good idea at that point what type of law school that will be a likely option. As far as age goes, at 22 you will likely be one of the youngest in your law school class.
