About PrepTest 155

Which section of PT 155 is experimental?

Section 1 (Logical Reasoning) is the experimental section on PrepTest 155. 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 155 from?

Most of PrepTest 155 was first given in November 2019. LSAC rebuilt it from two older tests, with no logic games: Sections 2–4 from PrepTest 89 (November 2019) and Section 1 from PrepTest 92 (June 2020).
