Hi Syamee,
I had written a nice long reply and then my silly comp hanged. It was so frustrating and I couldnt even copy the text.
Anyway, here I go again.
Running the exe is the only way to get access to the contents of the material. The data is not stored in documents or text files. It's a program that runs on ur system. And these too have no explanations. In addition to the CR and RC material I think it has SC's too. A small link will be there, u gotta search for it.
The sample test has at least answers(that too reliable for sure). Many of the CR's of this paper are discussed in this forum. You just have to search the posts ( like I did).
If you really want explanations to lsat questions, I have some other expensive options for you
You can buy lsat prep material from kaplan,PR or you can buy testpapers with explanations from LSAC or kaplan. Just to give you an idea,(pls don't flip) one lsat paper (from lsac) with exp costs 17$. the kaplan one(has 2 tests) is around 20-30$.
