DON'T freak out this week and take too many tests or practice sections. You will stress yourself out, burn out on everything LSAT, and ultimately destroy your chances of getting the score you want. Do one or two difficult games, one or two reading comp. passages, and then go through the types of arguments. Studying the arguments saved me on the LSAT the second time I took it because I knew what the test writers were looking for. Make some flashcards or something. However, DO NOT look at anything LSAT Thurs or Fri. If you're the type of person who does better on the third section on, get up on Saturday and do a few questions in each section. If you're the type to burn out after the break, don't do ANYTHING after Wednesday. You're as prepared as you're going to be.
Good luck!!
