I'm late to the game with the LSAT Trainer, and I would have to agree - put down the Bibles. They're incredibly clunky. I prettymuch only use them for practice material at this point, but there is a bit of overlap between the two.
... like, most personal statements are pretty general across the board so ... that you could send to prettymuch every school you apply to ... I'll have to do much to change it once apps ...
Also, while the major groups are prettymuch the same across different resources, once you get to the secondary and tertiary types you'll see a difference in how things are classified.
