Not ready for the practice tests? Our Study Mode feature allows you to study one question at a time, 100% free as always. Study Mode uses the same questions, answers, and explanations as our Free Practice Exams, but displayed in a singular format. The Study Mode feature is perfect for beginners or a quick study session. This feature can be found by selecting a CompTIA Certification on the left, or choosing one of these CompTIA Certifications: A+, Network+, Security+, Server+.
