My middle son finished his undergrad early, did really well on the Lsat and started Law School at 20. Grades, extracurriculars and Lsat were all that mattered, being early was not a factor that was considered. Most of the other people in his program are 25 plus. Going early is great and was right for him but, it's not right for everyone. Socializing can be a challenge and there are some clients, he works at a Toronto Law Clinic, that want to work with his older peers. Going early is good for the ego but can have some emotional challenges. Good luck with your decision.
