I purchased and used the LSAC web based application last year. The only thing that I didn’t like was that LSAC advertises that you can fill in common information (undergraduate education, work experience, etc) and it will flow through to every application. However, I found that my common information didn’t fit on every application so I had to go to each application and adjust accordingly.
Other than that, I liked the web based system. It allows you to save applications and work on them bit by bit, and sending them to the school is a snap. As soon as you click send the application and any attachments are received by the school, so there is no need to worry if your application ever made it into the hands of the admissions committee. Many schools offer the option of paying the application fee online, and for those who don’t, the LSAC provides a letter that you print out and mail to the school with payment.
Also, it is a three or four step process to actually "send" the application...so the risk of sending an incomplete application by mistake is very very low!
I think it is worth the $54 to have a “paperless” application process!!!
