About PrepTest 139
Which section of PT 139 is experimental?
Section 2 (Reading Comprehension) is the experimental section on PrepTest 139. It's unscored: it's there so the test has four sections, like the real LSAT, but it doesn't count toward your score. The other three sections make up the 77 scored questions.
When is PT 139 from?
Most of PrepTest 139 was first given in June 2013. LSAC rebuilt it from two older tests, with no logic games: Sections 1, 3 and 4 from PrepTest 69 (June 2013) and Section 2 from PrepTest 60 (June 2010).
