They are pretty ok... should be used as a last resort though... so I would suggest saving them till may/ June... the first one you would have done... its basically June 2007 all over again with Indian names... the others I think are different.
@profile427 there are more factors that will go into this than just your LSAT score. For example if you are a URM then your GPA would give you a shot at most of the T14 even with a 160. But of course, higher is always better!
Admission with those numbers is not unheard of, but very unlikely especially for a non-URM candidate. Odds are you won't get into any T14 with those numbers, though T20 is a reasonable bet. If you're okay with that, fine. If not, retake.
... it matters what type of URM you are as long as ... student body but still enjoy URM status due to the demographics ... . While some schools may use URM as a specific numbers boost ...
Wish I could point you towards more specifics but I know I've read that you can equate URM status towards at least a few LSAT points. Make sure you write a good diversity statement!
