Is there a penalty for guessing on the LSAT?

Bernadette Bernie Chimner began teaching in 1999 for a major test prep company. Although she loved her job teaching and tutoring, she found herself unhappy with the company’s stance toward its students and teachers. Her quest for a company with a philosophy more akin to her own would take her through two other large test prep companies before she finally arrived at Griffon Prep. She brought with her an extraordinary reputation as an exceptional instructor and a vast knowledge of both the LSAT and the GRE. Bernie is extraordinary in her dedication to her students. She spends her time after class and during break answering questions and she goes to lengths to make sure she is in touch with her students between classes as well. As a teacher, she is patient, friendly, and gifted at explaining questions in a simple way. Bernie’s skillful teaching is backed by an array of exceptional test scores. She obtained a perfect 180 score on the LSAT in June 2005, has a perfect GRE math score of 800, and boasts both a GRE verbal score and a GMAT score in the 99th percentile.
