CompTIA Social Networks

CompTIA A+ is one of the best certifications in the world. I would rate this certification higher than many other vendor certifications because it tests a candidate's knowledge on all fields of information technology and not on one particular domain. It's a gate pass for your first job. Thank you CompTIA for enhancing my life and blessing me with a better future.
