The website has a better description than I'd be able to write: Summer Conditional Program
The Summer Conditional Program permits invited students lacking the traditional indicia of success to demonstrate that their ability transcends their quantitative credentials. Applicants possessing credentials close to those of accepted students may be invited to participate in a three-week set of week-long units on various topics beginning in mid-June. Each unit is taught by a full-time member of the law faculty. At the end of each week, students will be tested on the material covered during that week. Students will be graded on a point-scale system; students in the top 20% of the class will be admitted to the fall entering class. The performance in law school of students admitted through the Conditional Program has been strong.
I don't think I would go for this, its too subjective and risky especially since I don't already live in Miami.
