Some people just don't test well. I would suggest for the people with the low scoring applications to send out applications to a whole bunch of schools. A great GPA will offset a horrible LSAT score. I would also try to explain the low score in a statement without a negative attitude, i.e. highlight your positive aspects instead of blaming LSATS.
I am in a similar situation but in a different score band, I didnt do as well on the LSAT as I did on the practice exams (on the last practice exam I received a 170) and I got a 160. I am trying really hard to get into some Ivys as i have a 3.8 in mechanical engineering (which is an extremely challenging major!!) but Most likely I will not hear anything till april.
Dont ever give up, if you dont get accepted this year find a job maybe as a paralegal and work for some time (waiting 5 years will erase those scores). I don't have the option of waiting because i was granted an educational delay from the Army and I have to take it next year.
I wish you the best of luck~~
