Since my last post, I received the CD-Roms in the mail for Phase 1 of 63J10 school. The computerized Army is a Microsoft Army. The disks I received were dated June 2002 and would not run on a Mac. I have a Mac Powerbook, so I bought a cheap computer to run these disks. My son will eventually need a Windows computer for school, so it was not a waste of money. The courses are well organized and I have completed two modules so far. One of the instructors from the 63J school called and asked if I had the materials and wanted to make sure I had time to finish phase 1 by March 8. So after being nowhere last week, everything is going well--and I own a Windows-based computer.
