Don't be intimidated by the "youngins" running around campus. Non-traditional/Second Career/Older Students do very well at St. Mary's. In my section, we have a number of people in their 30s, 40s, 50s... Several on the Dean's list, most are in the top 25% of the class.
You need a "workmanlike" attitude to succeed in law school and "working" like its a job (a 50-60 hour/week job) is more common for older students.
