I can tell you exactly:
Top 15 students in the FT day division after 1st year grades come out get $29,900 scholarship for their second year
Top 5 students in the PT evening division after 1st year grades gets $21,230
Top 15 students in FT day division after 2nd year grades come out get $24,000 for third year
Top 3 students in PT evening division after 2nd year grades come out get $17,000 for third year
Top 2 students in PT evening division after 3rd year grades, gets $17,000
That should work out to full scholarship for your second year (because they don't want you to transfer out) and then roughly 80% for your second year.
For me, I got 50% coming in, 100% second year, and 80% third year (they gave me another 20% grant for helping with academic support -- assist 1Ls with study skills) so I ended up with 100%, still waiting for grades after third year, but hope for the same deal for my 4th year (I'm in the evening division).
For law review (in case you care -- and you should): The top 5% after first semester grades come out are invited on in February; top 10% after second semester grades get invited on in June; then there is a write-on competition in August for those that did not grade on.
