Just about every one of the students I've tutored that has taken an LSAT prep course has told me that the course was largely a waste of money. However, my sample is biased because people that weren't satisfied with their prep course are more likely to seek extra tutoring. For those of you that have taken an LSAT prep course, what are your thoughts? Which course was it? Was it an efficient use of your time? Did you improve a lot? If you could go back in time, would you still choose to do the course?
