content: I have been looking for a book like this. Trust me. Just follow the book through from cover to cover and take notes for things he emphasizes and then do the practice questions in the book and on the cd. You will pass the exam! Make sure you have a computer to screw around with as well. His tips can be tested and it will help steer you out of confusing questions on the exam because you know which scenarios will not work. I just wrote the core hardware and scored a 913 and i expect to do the same for the operating systems exam next week. (...) remember Comptia's tests are adaptive and you only have thirty minutes. with his book i was done in eleven minutes. Way to go Mikey. Keep up the good work. Every computer technician should have a copy!
