Excellent Study Bundle! Don't Let Negative Reviews Fool You!
Format: Paperback
I received the four books in a box, and they arrived brand new and exactly as described. These books are truly great for learning and easy to follow.
I was almost discouraged from ordering because of some of the negative reviews, but I'm so glad I decided to see for myself and ordered this bundle deal.
While the internal pictures and screenshots are not high definition or in color, they are perfectly easy to view and follow along. The author does an excellent job of guiding you, telling you exactly what to look at within the picture to follow along and understand the concepts. All the screenshots are spot-on and very readable.
This is my first set of A+ books from Sybex, and I have the two main study books, the review guide, and the practice questions book. Wow! What else can I ask for?
I used to rely on the big books with the golden covers, but they didn't have the latest editions. Too bad for them—this is a huge gain for me! Thank you, Sybex and Authors!

reading this helped me pass the A+ core windows 1 exam and security plus
Format: Paperback
Problem is that I am 63 years old having earned the certificate and the industry doesn't seem to welcome older workers . I used to help maintain a fleet of printers at two large companies. I have read about other more experienced tech workers in their 50s getting jobs now working in pharma working at sterilization technicians because IT seems to be puking jobs.
