Average LSAT of last years class was 157. Average GPA 3.3. Based on these statistics and the statistics of all students applying to law school from the LACAS website; 82% of all students applying last year were below Southwestern's mean.
If SW was attached to an undergraduate university and had greater name recognition they would be in the top 100.
According to www.cal.bar.gov
Southwestern has the 3rd highest number of active alumni in California (9,000). Not a bad place to graduate from if you need to network.
Southwestern, can't legitimately be considered a back up for most law students (see stats already noted). Moreover, they only accepted 24.7% of the people who applied last year. Pepperdine: 27.6%; USF: 25.6%; Santa Clara: 25%; Loyola: 19.7%.
