A+

CompTIA A+ is the industry standard for starting your IT career and appears in more tech support job listings than any other IT credential. It requires two exams: Core 1 focuses on hardware and networking, and Core 2 covers operating systems and security. You can take either exam first or prepare for both together. V15, the new version, offers the latest material, while V14, the retiring version, is best for those already studying and is available until September 25, 2025.
