According to its website, "After careful consideration of an applicant's file, the Committee on Admissions will sometimes accept into the part-time program applicants who have applied to enter as full-time students. This decision is reached after a thorough review of the academic transcripts, LSAT score(s), and other material included for consideration. Another factor that plays a significant role is a view of our applicant pool as a whole. The part-time program allows applicants to begin law school carrying a lighter course load for the first year. Transferring into the full-time program after completion of the first year in academic good standing (C average or better) is accomplished with a request to the dean of students. Law school can be completed in three years by attending two summer sessions. Required second-year course work will be completed in the evening when a transfer of divisions is granted."
Not sure if this is binding though.
