If you know your stuff you will be OK, but you cannot fake it. You cannot know HP and Compaq desktops and get through it. You need to know more than the hobbyist who has built a couple. You can find many sample tests online. If you want to pass it, read a book or two. All the A+ preparation manuals I have seen are preparation enough. I know a lot of skilled technicians who did not pass it the first time through. You should know SCSI, and the concepts behind IRQ's. You need to know the nomenclature, and have experience with motherboards, pci cards, isa cards, modems, and power supplies going back to 1994. You must have a good working knowledge of 98SE, ME, W2K, and XP. You should be able to recognize components in a drawing. Be able to discuss memory from 70 pin DIMMS to DDR. Some guys get an easy test, but not so many lately. The test has been revised to test you where it senses you have weaknesses. These changes that occurred last fall have given people trouble. Before, you could get lucky and have enough general and technical knowledge to pass overall, even though you had some lapses. Now the test takes a closer look at your lapses to see if they are knowledge gaps.
