Score was 567, not great, but since I really don't like learning about old software that I'll never use, I'm happy I passed. I used A+ Complete, the 80/20 Guide, The A+ Exam Guide and the free test practice sites. None of which I thought were very good. If I had it to do over, Mike Meyer's book keeps getting mentioned as a good study guide. Most of my questions were either 98 or 2000 related, almost none on XP. A lot on files, where things are stored, and attrib stuff. Had to mark several for review as it wasn't clear what they were asking, or I had just never seen the issue before. Of all the electronic tests I've taken, the OS exam gave me more headaches than any other. I'm glad its over.
