the A+ cert is good for IT professionals, and computer repairers. It won't do anything for computer science. However, it WILL help you land a nice job working with computers in college (think bestbuy geeksquad).
Doesnt geek squad pay like $9.50?
Yeah, GeekSquad isn't the high-point of Computer Diagnosis/Repair, but it's a job. In my area, $9.50 isn't bad for a retail position. In Northern California, it's pretty much the unofficial minimum wage.
However, just as recent as yesterday went paroozing (sp?) for jobs mainly under the searches "Helpdesk", "Desktop Support Technician", "Network Technician", and "Network Analyst". Most of the available jobs were DST positions and nearly all of them either desired or required an A+.
Most IT professionals don't really work with hardware, so the A+ really isn't as important in light of certs from the likes or Microsoft, Red Hat, Sun Microsystems, Cisco, Nortel, Oracle, VMWare, etc. But for most of the entry level jobs, you're running all over a 35 mile radius fixing office rigs for approximately $15/hr. If you're just starting out and you can't honestly put CCNA, MCSA, or RHCT on your resume, the A+ is your key to your foot in the door.
