Thanks so much for the info, Charles and digip! Especially digip for taking the time to explain and suggest so many things! Yes, I have built several PCs from the ground up without any problems. I have been skimming through most of the books and stopping in the areas that I feel I might need a refresher on. They all do come with a CD that contains practice exams and one has flash cards to study with as well. Thank you both again for the suggestions and good luck Charles on your two exams!
