Question about books to study for A+
I am just starting out, looking for books to study for A+ cert. I have a few books for A+ but they are from 2001 and 2002 I have no idea how many things may have changed since these books came out 11 or 12 years ago. I just wanted opinions on whether I should/could just use these books or if I be better off buying a new one? Also, if anyone can tell me how drastically the information may have changed from then to now?
