About PrepTest 138

Which section of PT 138 is experimental?

Section 4 (Logical Reasoning) is the experimental section on PrepTest 138. 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 78 scored questions.

When is PT 138 from?

Most of PrepTest 138 was first given in December 2012. LSAC rebuilt it from two older tests, with no logic games: Sections 1–3 from PrepTest 68 (December 2012) and Section 4 from PrepTest 60 (June 2010).
