I started law school shortly after turning 21. I had entered college intending to graduate in 3 years but became seriously ill the first year and wound up taking the full 4 years; I had 24 credits going in. Had i not become ill, I would have gone to law school at 20. I was one of the youngest in my class and graduated second. I see no reason why the OP should not go straight to law school. Apparently, it is beneficial to have some work experience before pursuing an MBA, but people I know who went to law school after being out of school for years had a tougher time than people like me, who powered straight through. Being in the swing of studying and in the school mode is a positive for law school.
