CompTIA A+ is the industry standard for getting a job in technical support and establishing an IT career. A+ is not just about PC repair. A+ candidates are better prepared to troubleshoot and problem solve a wide variety of issues, ranging from networking and operating systems to mobile devices and security.
To get certified, you must pass two exams from within the same CompTIA A+ series, e.g. 220-901 and 220-902, etc.
