I took Blueprint. It was awesome and I highly recommend it. They are very entertaining and actually make class fun, not boring. The instructors are hilarious, friendly, and the class is highly interactive. Also the examples they use are hilarious
However over that, I recommend self study with powerscore books and lots, and lots of practice tests. I regret spending my hard earned money b/c I'm pretty sure I would have gotten the same score w/o the blueprint class.
I did Blueprint too, the online course. I didnt really have a whole lot of options, since I was working full time, living in the middle of no where (I think there might have been a Kaplan course like 50 miles away), and needed something that could be on demand and equivalent to a full course. Honestly, I am really glad that my options were limited, because I think that was the best course for me. I took the December '10 LSAT and scored a 159, after studying lightly for a month or so. I decided to try to seriously study and by the end of the BP course, my PTs were in the 172-178 range. BUT, I studied my fucking ass off. I don't think most people do all of the homework, but I did (I studied for about 6 months, 2 months intensively). By the end of the course, the homework would be like 113 LR Question Mix, 5 LR Sections, 2 LG Sections, 2 RC Sections, RC Mix, LG Mix... I did all of the additional PT's they provided. They also had video or audio explanations for pretty much every questions. They also reshaped the student home page where you can grade your homework and it will spit out a ton of data for you to assess yourself with (with PT's too).
Here is the final reason I recommend them: 3 weeks or so before the October LSAT, they were able to work something out with LSAC and put up the June 2011 LSAT to download and had video explanations for every question. I thought that was pretty amazing and it really made me feel much more confident going in last Saturday. To me, that demonstrated that they really cared about their students. They could have been like, "Hey we have the June 2011 LSAT for you to download for $20."
I know this sounds like I work for them or something and I have not posted on here a lot, but I just really like this company and they helped me a lot. It was well worth the money for me.
