If anyone in Philly needs a tutor, now that I'm being laid off for the summer, I'd be happy to do it for $30 an hour.
The benefit of having a tutor is that, if the tutor him/herself scored high on the LSAT, they know what steps you can take to increase your score. I, personally, would give you a prep-test and then custom form a schedule to address what I deem to be your weaknesses. At the end of each test, we would review your incorrect answers and the logic behind them, as well as strategies you can take to keep your mind focused.
All the testing supplies would be free of charge, of course. And note that I do not endorse any dietary supplements.
