Barron's How to Prepare for the ASVAB by Barron's Educational Series Inc (2006, Package)

I read the reviews of just about every ASVAb Prep book out there. I bought the "Barron's book, which was one of -if not THE- most expensive book available. So the question is "Did it help?" Without any doubt, yes it did. Is it worth the MSRP of $29.99? No. Maybe $15.00, at best.
Having taken a the ASVAB in 1993, I was unsure what to expect. I had five days from the time I decided to take the ASVAB to prepare for it. I shopped around online and at retail locations. I bought the Barron's book, and was broken hearted when I bombed the first practice test in the booklet. The second and third tests weren't much easier, but having reviewed my previously missed questions and getting back up to speed in math and general science, I did fairly well on the fourth and final practice test.
I took the ASVAB on August 6, 2007 and was pleased to score extremely high across the board. The test itself was a bit easier than the Barron's book, which contains not a few errors, both factual and printing/editing.
The CD-ROM featured the same hard-copy practice tests, it's not much help beyond the fact that my ASVAB was administered on a computer. I had no problems with any virus that was rumored to be on the CD.
So how did I do?
When I first took the test in 1993 I was still in high school, and my GT(General Techical) score (which is based generally on your VE and AR scores and is the standard baseline for the Army) was 123 , but it was a much different test. After serving four years in the military and then getting a Bachelors degree, the Barron's book helped me get a GT score of 142 and none of my line scores were lower than 132. I did not think the GT score went above 140, I guess I was wrong or things have changed. I attribute much of my success on the ASVAB to the practice tests in the Barron's book and can say that some of the questions will appear almost verbatim in the actual exam depending on what version you take.
A decent book, perhaps one of the better ones on the market, shop around and take the test seriously.
