Khan Academy
Khan Academy provides an extensive library of free, high-quality educational content designed to support learners at every level. With over 10,000 video lessons and 50,000 interactive exercises, the app covers core academic subjects—such as arithmetic, algebra, biology, physics, chemistry, U.S. history, civics, and personal finance—guided by expert instructors. Each lesson combines concise video explanations with practice problems that adapt in difficulty based on your proficiency, ensuring that concepts are mastered before moving forward.
The app’s adaptive learning algorithm creates personalized study plans, highlighting areas in need of review and celebrating milestones with badges and energy points. Offline access lets you download lessons and exercises to continue learning without an internet connection, making it ideal for classrooms or on-the-go study. Teachers and parents can create free “classrooms” to assign content, monitor progress in real time, and provide targeted support using the companion Coach Dashboard.
Beyond core academics, Khan Academy offers test-prep resources for standardized exams such as the SAT, MCAT, and LSAT, featuring full practice exams, strategy videos, and step-by-step solution walkthroughs. The Career section offers modules on coding, career readiness, and college admissions, empowering learners to build practical skills and plan next steps.
The app’s minimalist interface focuses on learning without distractions, while progress tracking charts and mastery scores visualize your growth over time. Regular content updates expand subject offerings—most recently adding advanced topics like macroeconomics and differential equations—and refine existing materials based on user feedback and pedagogical research.
Backed by a nonprofit mission to provide a free, world-class education for anyone, anywhere, Khan Academy has engaged over 155 million registered learners globally. Its combination of adaptive learning technology, comprehensive content, and supportive community tools makes it a go-to platform for students, educators, and self-motivated learners seeking academic excellence and lifelong knowledge enrichment
