Is it the setup that is taking up the most time or the individual questions? Is there a game type that gives you greater difficulty? (linear, grouping, pure sequencing,...)
If your accuracy is good but time is a factor, one possible approach would be to just concentrate on three of the games and skip the game type you find most difficult. Lets say you skip a game that has 5 questions and just guess D for all the questions in that section. You will have about a 1 in 5 chance of getting a correct answer for that game section. If you were accurate with the rest of your game questions, you would only have about 4 incorrect answers which would be very good, especially if games are your weakness. Lets say as a worst case senario, you get 4 wrong on each of the other sections. If your LSAT is 101 questions, that leaves you with a raw score of 85 and a scaled score of about 169.
