Learn What to Study for the CompTIA A+ Examination

In order to earn the CompTIA (Computer Technology Industry Association) A+ certification, candidates must pass two exams. These two exams include the 220-901 and 220-902. Both exams measure one’s readiness for entry-level IT positions. Typically, candidates have 6 to 12 months of relevant experience prior to taking the exams. Candidates with the CompTIA A+ certification are recognized by their colleagues as able to assemble components based on customer requirements; install, configure and maintain devices, PCs and software; troubleshoot common IT problems; and provide appropriate customer support.

The CompTIA A+ 220-901 is comprised of four content areas and each area carries a different weight:

• Hardware 34%
• Networking 21%
• Mobile Devices 17%
• Hardware & Network Troubleshooting 28%

The CompTIA A+ 220-902 is comprised of five content areas. Once again, each content area carries a different weight:

• Windows Operating Systems 29%
• Other Operating Systems & Technologies 12%
