A) The LSAT is purely a test of technique, not of subject matter. The only "content:" involved is the specific content provided for you by the reading passages, arguments, and puzzles as supplied in the exam itself.
The best way to see what an LSAT is like is to attend one of the
free real-LSAT exam-and-class events we run at various area colleges
and universities two to four times a year. At each one, we present
a REAL LSAT -- not a simulation -- and then give an introductory
class, using specific Questions from the exam itself. You also get
an extremely detailed Personal Performance Analysis® showing
what you already did the LSAT way and what you did not, section
by section, Question type by Question type, and even broken down
by trap-answer type. You can call us for the next round, or see
a schedule here.
