Definitely not toolate, December is the more popular date for the LSAT. In fact many schools accept the February LSAT for admissions of the same year because of how low applications are.
No not at all. In fact February isn't toolate for a lot of schools. That being said I would avoid sticking to arbitrary timelines if you aren't ready. Law school will always be there for you so take your time and take it only when you're ready.
@esteerose You could try, but keep in mind that it's toolate to change it at this point. If it would ease your mind though, you might as well give it a shot.
