Guys, sorry for disinformation and not quick reply. I did not note the phase "one month". It required me 8 months to improve my score. Sorry again.
As for my preparation it was ordinary: all Manhattan books (except CR) and their 3 tests out of 6 in a month before the real exam (710, 760, 700), CR bible, LSAT tests. I also solved problems from this forum.
to siddaggarwal: I live in Moscow. But I am a great admirer of 2 guys from Uzbekistan who posted brilliant debriefs on this forum. They were my examples to follow to, but unfortunately I could not achieve their results. As for your next question. For me it is impossible to increase score on 60 points in a month and a half. But I read posts of some guys who could do so. I think they are born brilliant, me not, and therefore I had to spend so much time. But may be you could.
