The solution to your problem sounds like it lies in your ability to market yourself to Case. I don't think that you should retake the LSAT now without doing sufficient warm-up prep work. So, that said, the question becomes how to best position yourself to get accepted to Case. I think the answer is that you sit down with the admissions folks at Case and lay it all out for them. If they accept you, you will come, so thus they aren't hurting their selectivity numbers by letting you in. Plus, your GPA is very good for them. Finally, you will not be asking for money from them because you have money coming from somewhere else. Make yourself more attracive to them.
