This might be biased:
I studied for it for 8 months then failed the first test (by a small margin). Then I stopped studying for it. It's an inch thick and a mile wide: In other words it's easy but theres alot of info you gotta memorize and and your brain needs to become a giant storage device.
I would recommend going for cisco certs or microsoft certs or something because they'd be more recognized/ distinguished so to speak.
A+ isn't exactly the most amazing certification around, alot of people think it's stupid. I think it's overrated. Anyone can fix a computer. Why memorize the different fire extinguishers and what to do when someone is being electrocuded? Those should be a different test.
Theres alot of good resources and books out there--and alot of bad ones. Some books prepare you, some don't properly prepare you. Visit forums, ask questions, ask about what are the best books.
[edit]
Oh and the structure is somthing like this:
Test 1: Required
Test 2: 1 of 3 options depending on which A+ Cert you want
