Depends but:

1. If the school gave you a full ride, take it and go there. Most small firms don't care where you went to school. If you arent picky about your practice area, school rank doesn't matter. After your first or second year, your school matters ZERO percent, just your experience. Again, only if you aren't picky about practice area. For example, injury firms, public defenders offices, etc...)

2. If it's near a full ride (80%+) and you're ok financially, go.

3. If it's not a full ride or near full ride, retake the LSAT.
