I used mike meyer's cert passport for a+ in conjunction with professor messer's 801 and 802 study guide and I passed just fine. Exam compass also offers free practice tests which will help you solidify the understandings of most of the concepts needed to pass. I'm using the same author for studying for my Network+ and professor messer's study guides.
