Powerscore was created back in 1997 by test prep “expert” Dave Killoran based on his experiences in the industry. He believes his methods help students succeed with higher test scores on a number of different types of standardized testings in addition to the GMAT and GRE, including the LSAT, ACT and SAT exams.


Killoran and his colleagues’ take a more standardized approach through the use of lectures, lessons and discussions, similar to a traditional classroom environment. Powerscore also offers private tutoring, either live online, in person or via telephone. They have published and are selling a number of GMAT prep books including:

  • A trio called “The PowerScore Verbal Trilogy” ($69.99)
  • The GMAT “Bibles” for reading comprehension, critical reasoning and sentence correction (available individually for $24.99)
  • Official guides for 2016 including an overall version ($39.99), verbal and quantitative reviews ($19.99)
  • Undated official review guides are priced at $18.95 and $12.95 respectively, similar to the 2016 editions
