I see alot of guides/books out there. Is there one that is better then the rest?
Some of the guides/books are for CompTIA A+ 220-301, 220-302, 220-601, 220-602, 220-603, 220-604, etc. I assume the 220-*** are versions? What is the most recent version? Which should I purchase?
How long does it take to complete the tests? There is a test for hardware and software?
