December 2010 LSAT Logic Games, PrepTest 62 Analysis

I've just about finished analyzing the December 2010 LSAT, which will become PrepTest 62.

For today, here's the logic games data. I've broken down the games by their rule type and overall classification so you can figure out why you excelled (or had trouble with) a particular rule combination. The number after the rule type indicates how many rules there were for that particular type, and they're ordered by density, not how they appeared on the LSAT.

The story is the same from the October 2010 LSAT logic games in terms of long-term trends in the analytical reasoning section. The more traditional (sequencing) games are more difficult by adding meta-cognitive tasks like "restate the rule." 


This trend has even continued into the most difficult game--the stained glass windows--which had one rule each from the entire grouping strand mixed with fluid slot assignments. In addition to the tricky rules, it also had four questions about how actors in a certain fluid position affected both of the other fluid groups! Historically, the "[if] could be [there]" questions are extremely limited, perhaps having one or two on an entire games section!

Look for the logical reasoning and reading comprehension analysis later this week!

Sequencing (86%), General (14%)
  1. Tree (2)
  2. Barrier (2)
  3. Slot (1)
  4. Min/Max (1)
Game 2 - Artisan creating three stained glass windows
Grouping (71%), Assignment (14%), General (14%)

Here's the diagram I used for the stained glass windows game: note the three separate groups that must have two and could have up to four each. Be sure to figure out the must mother f-ing remembers!
