unfortunately, some training companies have jumped on the bandwagon and are charging exorbitant amounts for what is a fairly basic level course.
Recently browsing in Waterstones, I noticed very reasonably priced books that cover all the content of the A+, at a fraction of the cost of a training course.
Probably worth a look!
Personally, I have actually done this course, but opted not to do the exams, as it appears they are not recognized very much here in the UK. In fact, most people have never heard of the A+ course!
