Very Useful
Format: Paperback
I used these for my A+ exams and I didn’t really end up reading the material. I more so used them for their practice exams. That’s only because there’s a lot of information to digest and I was in a rush to take the exams. I still passed so I find that they are well formatted. The questions imo needs to be read more throughly than the exam questions themselves.

It’s very hard to prepare for a comprehensive certification examination studying from an incomplete text. FYI, the book was purchased new and not damaged, it was bound that way
