It is too late now, but reading an "A+ Reference" and a "Network+" book would definitely help! There are versions of the A+ book with 250 pages and more in-depth (overkill) versions with 750 or 1,050 pages, so try not to be intimidated by these choices. Sometime ago I think I spent $34.95 for one particular version of a comprehensive guide to A+ topics (a softcover book), and that seemed a reasonable price at the time.
There are versions of this subject matter aimed at "people in a hurry" (but with at least a month to spare for reading) that cost hundreds of dollars and "guarantee" you will pass the exam. Are they worth the money? Perhaps if that is the kind of disposable income you have to spend.
Someone else here wrote that A+ was an easy certification to get, and that may be the case but everything is highly individualized and dependent on your memory (recalling facts) and comfort level with the subject matter. Some people are also great at working on PCs but choke when it comes time to take the test, and we (as commentors and respondents) need to remain aware of these things also.
Good luck!
