I decided to burn a couple hours running through it... it actually didn't take that long, and it's something I recommend since it's a good concise summary....
..also I saw a comment on another blog about some guy who counted the number of concepts that showed up on his/her actual exam... and he/she had about 90 questions linked directly to something on that file... so who knows. Doesn't hurt and the more the merrier, right?!!!
I have a 36 page one - modified in 11/2005 (don't have the 46 page one).. I have another 20pg one that was last modified on same day... PM me and I can send it to you if you would like
