The Kaplan Test Center provides a very high quality, well organized program. Any student looking to up their LSAT score should definitely consider this course.
One LSAT Center owner informed me that most of the courses will up your score in a range of 5-7 points. In my case, Kaplan out did that.
Pros: Kaplan is a nationally recognized program that is renowned for their test preparation materials for many different subject areas
Instructors who have taken the exam and scored at or above a given level
A dedicated test center with past exams and quiet rooms to use at your disposal
Well located, many course slots.
Cons: Very expensive- over $1000 for the classroom course. Private tutoring sessions up this significantly
Class groupings are not divided by score level. This basically means if you are excelling, the lower performers in the class may very well hinder your experience
Puts a great deal of emphasis on the homework
