You may or may not understand anything, that's ok. Just go through and if it peaks your interest. Go for law. If not. Then leave it. Political science and constitution in particular is the basics. Later on in law school you'll study anywhere from 40-50 subject. You won't love all of them. Still that's how it is for everyone.
