Before I took my first LSAT, my practice tests ranged betwenn 161 - 168, and I wrote a 155 on the actual (all practice tests were timed). Before the second LSAT, I took many more practice tests, which ranged between 160 - 164, and I wrote a 163 on the actual. I don't have a good explanation for why the first LSAT was below my practice range. I may have been just too nervous. By the time I took the second LSAT, I was so familiar with the LSAT that I wasn't even tired when I finished. The approach of not taking timed tests, at first, sounds like good advice. I took all my practice test timed and never significantly improved my score. If I were able to go back in time and prepare differently, I would try to get every question correct without worrying about time, at first; then, I would work on timing.
