What Is Khan Academy?
Khan Academy is a non-profit organization that provides free, high-quality education to anyone, anywhere. Students can access Khan Academy on the web and on mobile devices to learn math, science, reading, computer science, test preparation, and economics, and much more.
The platform does not require a student to follow the schedule exactly like they would in a classroom, but instead lets them work through lessons and practice at their own speed. This flexibility is especially helpful when a student has been absent from class, requires extra practice on an old topic, wishes to cover and rehearse an old topic or simply enjoys learning outside the classroom.
The latest annual report from Khan Academy for the 2024-25 school year showed the platform had 189.6 million registered users, 104.9 million learners who were active users on an annual basis and 66.8 billion minutes of learning. The platform is used in 190+ countries and 55+ languages, showcasing the widespread reach of the platform.
The core concept of Khan Academy is straightforward: Making learning easier when students can get an explanation, try some questions, see where they go wrong, and then try again. What if there was a digital study partner to help you review fractions, understand a biology concept, review a historical topic, or prepare for an exam?
It’s not a substitute for a great teacher but can be a good supplement outside of class. According to the platform’s official description of the app, the learners will be able to gain knowledge of thousands of skills with interactive exercises and mastery levels, and progress will be synced with the platform’s website.
Why Khan Academy Is Popular With Students
A main benefit that Khan Academy offers to the students is its accessibility and structured learning. Many academic subjects can be reviewed by a student without the need for costly tuition or private tutoring, or a vast library of books.
Lessons, videos, exercises, quizzes and learning experiences that take students further are available on the platform and can be utilized to complement regular school lessons.
If a student is having trouble mastering a concept, it may be less stressful for him or her to stop the lesson and start the explanation again than to try to grasp it in a rapid lesson. For students that already know a topic they can move on instead of waiting for the rest of the class to get to the next concept.
One thing I liked is that Khan Academy is built not around videos alone, but practice. You can address questions, helping students to familiarize themselves with individual skills, thus making revision more active.
According to Khan Academy, its research on efficacy resulted in about 20% learning gain in students who logged between 18 and 20 hours into the math platform over the course of the school year; another study linked learning of about 60 or more additional skills to around 20–30% more learning in the students studied.
The results of these studies are the products of Khan Academy’s own research using large student populations and are intended as evidence from the studies alone and not as a promise of results for all students.
Is Khan Academy free?
Yes. According to Khan Academy, their essential learning platform is 100% free for independent learners, teachers and parents. According to the group, it is a nonprofit dedicated to offering a world-class education to anyone, anywhere, at no cost. Students can view thousands of classes covering areas such as Math, Science, Reading, Test preparation, Computer science, and more without having to buy a yearly subscription to these courses.
This is a free model of particular significance for students who are not well resourced in their learning. A learner can access a significant amount of educational material using their smartphone, tablet or computer and access a significant amount of internet without paying for all of the lessons.
There are other products and services available for schools and districts for which the pricing is different, however. For instance, Khan Academy has paid information about district services listed on their website, but they offer the basic independent-learning experience for free.
What Students have access to for Free.
With Khan Academy students have lessons and practice in a wide variety of academic subjects. The material that is available to a single learner may differ across subject, grade, country, and curriculum, but most of the school and college prep material is covered.
This can be very beneficial for students who are having difficulties as well as for students who would like more challenges.
The official platform now contains material on: math, science, reading, test preparation, computer science, financial literacy and more. Specialized materials are also available for students in a variety of science subjects (biology, chemistry, physics, etc.).
10 Key Subjects Students Can Study
The range of Khan Academy content is one of its strongest educational features. Instead of being a single-subject mathematics website, it has developed into a broader learning platform. Students can move from one subject to another according to their academic requirements and interests.
Math and Mathematics Practice
Mathematics is one of the areas most closely associated with Khan Academy. Students can use lessons and interactive exercises to study topics ranging from basic arithmetic and fractions to algebra, geometry, statistics, calculus, and other advanced concepts. This can be particularly useful because mathematics is cumulative: if a student has a weak understanding of fractions or equations, later topics can become increasingly difficult.
For students in Pakistan, Khan Academy also provides curriculum-aligned mathematics resources. For example, its current Grade 8 Math course aligned with the Pakistan National Curriculum contains 14 units and 176 skills, including real numbers, ratios, percentages, algebraic factorization, linear equations, geometry, information handling, and probability.
This type of curriculum alignment can make the platform more relevant to students who want to connect online practice with what they study at school.
Science, Biology, Chemistry, and Physics
Science students can use Khan Academy to explore subjects including biology, chemistry, and physics. Its science resources include topics such as forces, energy, waves, electromagnetism, chemical reactions, organic chemistry, genetics, evolution, ecology, and human biology. The platform also offers hands-on science activity resources for different grade levels, giving teachers and learners ideas for connecting digital learning with practical exploration.
For a student who finds a scientific concept confusing, the ability to break a complicated topic into smaller lessons can be valuable. Instead of attempting to memorize a chapter from beginning to end, a learner can study one concept, practice it, and then continue. This creates a more manageable learning path and can turn a difficult subject into a series of smaller challenges.
History, Economics, Reading, and Other Subjects
Khan Academy also extends beyond mathematics and traditional science subjects. Students can explore history, economics, reading, computer science, financial literacy, and test-preparation resources. This wider selection is useful because successful education is not only about solving equations; students also need communication, critical thinking, literacy, research, and financial understanding.
The economics material can be useful for learners who want an introduction to concepts involving markets, supply and demand, finance, and economic decision-making. History and reading resources can support students who need additional academic practice outside their regular classroom. The exact course catalog can change over time, so students should check the current Khan Academy website for the latest subject offerings.
How Khan Academy Helps Students Learn
The central strength of Khan Academy is that it allows students to combine explanation with practice. A student can watch or read a lesson, attempt exercises, identify mistakes, and continue practicing instead of simply moving through pages of information. This is important because knowing the explanation of a concept and being able to use that concept independently are two different things.
A useful way to think about Khan Academy is as a learning gym. Watching a lesson is like learning how an exercise works, while answering questions is like actually doing the exercise. If a student makes a mistake, that mistake can reveal where more practice is required. With consistent study, small improvements can accumulate into stronger academic skills.

This unit is delivered through a combination of practice, progress and mastery.
Students use the practice and mastery-oriented features offered by Khan Academy to gain an understanding of their progress. According to its official app information, it features interactive exercises and mastery levels, enabling learners to progress to a higher level of understanding for individual skills. Progress can also be synced, enabling students to keep learning on the website and app.
It can be especially helpful for students who may not feel good about being a “bad” reader or writer. If a question is tough, it does not mean it is the wrong answer, it may indicate that the student needs further explanation or practice. With that attitude in mind, students tend to stick with it, though sometimes they need help from their teachers, parents, or tutors to keep going when they persistently have problems with a concept.

Practice is yet another real-world use of Khan Academy. Students can reinforce their fundamental knowledge with appropriate lessons and practice tests prior to testing. Students can develop a consistent studying plan and review the key skills over time rather than cramming the night before a test.
It’s important to not use Khan Academy as an alternative to the student’s official course syllabus, but rather as part of a broader exam strategy. Students should make comparisons between the topic covered on the platform with the school book, teacher instructions, examining board requirements, and past papers. This is a way to help prevent spending too much time on content not relevant to the examination.
Khan Academy for Schools in Pakistan
Khan Academy is especially interesting for Pakistani students because Khan Academy has launched international programs and resources that include the curriculum. The annual report for the academic year 2024–25 reports that Khan Academy has started new KhanX programs in Bangladesh and Pakistan and has expanded programs in other countries. Khan Academy served 62.4 million international learners, educators, and parents that school year, the report adds.
Students can also access on the platform resources that are related with the curriculum. An example of this is the Grade 8 Pakistan National Curriculum mathematics course, which is made up of 14 units and 176 skills. [Khan Academy][4] If pupils are studying for local exams, it is best to use these resources as supplementary practice and compare with their existing Pakistani textbook and exam syllabus.
A Khan Academy app is available for both learning on the go and offline access.
For students who like to learn on their mobile phones or tablets, the Khan Academy app should make it much easier to learn. Students can use the app to “study math, science and other subjects at their own speed,” the official downloads page says, and “progress will be kept in sync between the app and the web experience. It also offers an offline learning solution, so that the learner can download videos to his/her library.
Offline access may be useful, especially in areas with poor internet access. A student can watch relevant material at a time when they have Internet connection and then watch it again at a time when they don’t. Khan Academy also explains its partnership with Learning Equality and Kolibri, an open source platform that will introduce Khan Academy to communities with unreliable connectivity.
Khan Academy Kids for Younger Learners
There’s an additional option for younger children called Khan Academy Kids. The app is geared to children about 2-8 years old and offers interactive activities, books, videos and lessons about early mathematics, literacy and social-emotional learning. According to Khan Academy, the individual app is free for families and teachers, and offers access to 4,000+ activities and books.
The design is a departure from the core Khan Academy courses because younger students typically learn better through more visual and interactive experiences. Parents can use the app with their kids and teachers can utilize classroom features. For families seeking an early-learning resource that is free, this can be a low cost starting point before children enter into formal classroom learning.

An other development related to Khan Academy is AI tutoring and teaching assistant Khanmigo. According to the 2024–25 annual report, Khan Academy had 2.0 million students, educators and parents who used Khanmigo this school year. Khanmigo offers personalised coaching for students and teaching assistance for teachers, according to the organisation.
AI can enhance digital learning experiences but students must be cautious in how they use it. An AI tutor should ideally guide a learner through a problem and get him to understand it, rather than just give him an answer to copy. Students should also ensure that they check information and abide by the academic rules of their teachers.
In the realm of education, AI can serve as a guide to foster learning, thinking, and questioning, but not as a substitute for it.AI’s most beneficial role in education is as a facilitator for thinking, questioning, and practice rather than as a shortcut to it.

There are significant benefits to Khan Academy: it is free for those students who learn on their own, it covers a wide range of topics, it offers structured practice, and can be accessed through both the web and mobile experiences.
It also has an international reach, having in 2024-25, reported that it had 189.6 million registered users, 104.9 million yearly active users, and is available to over 190 countries. The numbers reflect how much the platform has become a huge source of online education.
There are restrictions, as well. No teacher relationship and no classroom environment can be replicated by Khan Academy. When students repeatedly misunderstand a concept, it may be necessary to provide a direct explanation to some students.
Discipline is the key to online learning, and thousands of lessons are not necessarily a good study routine. The best way to do this is to use Khan Academy in conjunction with school teacher and class instruction, reading from textbooks, feedback from teachers, practice tests, and regular studying.
Khan Academy can be a second classroom for many students, and is free, flexible, and available whenever extra practice is required. It can be used to remind a student of forgotten maths, reinforce science knowledge, practice maths exam skills, learn about economics, develop reading abilities, or just out of interest to learn about a new topic.
The educational content of the platform rests on the regularity and the carefulness of the user. With regular study, active practice, a review of errors, and requests for human assistance in times of need, a free digital tool could become a valuable component of a far more substantial education plan.
