Just in case you ever wanted to get CompTIA A+ certified, check out Professor Messer’s free CompTIA A+ certification videos. This can help you prepare for the CompTIA 220-701 and 220-702 exams. There’s a bunch of videos and they’re all free.
Update – I am now CompTIA A+ certified:
Just passed the A+ cert. today. I thought I would weigh in on my experience and the usefulness of the various study material that I used. 0) It’s $173 per test, 2 tests; total $346; budget accordingly.
1) Prof. Messers video tutorials were great! Watch them.
2) Take the 30 question practice tests (2 of them; one for 220-701 & one for 220-702) provided by CompTIA; if you pass with 85% or better I think you can take the test without studying further, but I would recommend that you keep studying, just in case.
3) Take the practice tests in every book that you can find (go to your local book store or library and sit on the floor and take the test if you don’ want to buy the book). You can’t go wrong with practice tests as most of the answers are correct (BTW, not all the answers are correct; you’ll know which ones are wrong if you study enough; if you don’t notice any questions are wrong then you haven’t studied enough).
4) Sign up for a trial subscription to Safari online books. This will give you access to e-books and practice questions that you might not have had access to otherwise.
5) Interview with Robert Half Technology staffing services. This will get you access to their online learning material with practice questions too. You probably have a staffing company where you live. Ask them if you can access training material online before you are hired if you interview (don’t waste time interviewing if you can’t access the training materials beforehand).
6) ProProfs (Google it) has many practice questions. They are applicable, but some are dated.
I received 800+ on both my exams following this method after watching Prof. Messer’s videos last week and studying the practice tests this weekend (all weekend). I do have 21 years general experience and 7 years professional experience as an owner/operator of an IT consulting practice so I’m sure this played a part.
FYI: 1) There were no questions on modem AT commands (which is really sad since I knew all the practice exam questions on AT commands 
).
2) Of the 200 questions, there were probably 15% of the questions that were verbatim from the practice exams that I sited above (and about 50% that were paraphrased).
3) Know how to access the Windows XP virtual memory settings from the “Start” menu.
4) Know how to enable the Aero interface in Windows Vista (every which way you can think of).
5) “Net Use” was feature in about 5 questions related to connecting to shared folders.
6) There wasn’t really any math. There were 2 questions asking about DDR3 and they read, “Which of the following is DDR3?” (paraphrased) and the answers were similar to a) pc-this b) pc-that c) pc-the_other
Good Luck!
