They have the X manual on a CD now. You can call and tell them who you work for and when your class date is and they will send you a manual or disk. When I went thru X initial ICT sent me a manual a few months before my class. I spent a lot of time with reading it so that when I went to school I would read my hilights once each night and then just relax. I highly recommend that approach.
The only downside to the disk id that you cant Hilite, unless you have the advanded Adobe.
