“Free and easy to use. Good for studying.”

Ryan H.

If you're trying to learn things because you missed school that day, or you just want to review some things, this is a pretty good site. The videos are pretty easy to follow, and the interface is easy to navigate and find what you need. Though, I wouldn't suggest using it as the only source you're going to use. It's not the best, but better than many other sites. (Teachers, if you're reading this, use Khan Academy instead of the dumpster fire that is Edgenuity. Just don't make your students use Edgenuity.)

“This place sucks”

Alex H.

My dad made me do Khan Academy because i was 4 parallel universes ahead of everybody and i wasn't doing enough work for online school. I signed up for GRADE SIX math and the first question they ask me is duh, what's 5+3. another thing is you cannot restart quizzes. i accidentally pressed the wrong button and checked because that's what i always do and i had to do the rest of the quiz! Without all these fixes i cannot say Khan Academy is a good learning website for any reason at all.

I use their courses for every thing I wish to learn, every time before I start learning a new concept either in math or on the web, I check a course here. It helps you guide your mind on the right track. Of course, it cannot replace a university all by its own and for that you need to actually attend courses and be supervised by a teacher/lecturer. But for me, starting something new is the hardest part and Khan academy help me in that regard.

Khan Academy is great! you can learn so much. I learnt how to do trigonometry, then trigonometry with radians, how to solve some one-dimensional motion physics word problems, cryptography, and yet I'm still learning! It's a great way to study for tests and just having fun while learning!

I am a 47 year old who decided to finally get my high school diploma after 30 years. I unintentionally ran across Khan Academy in an attempt to 'brush-up' on math.

I noticed that Sal Khan has this 'relaxed' way of speaking while explaining how to do math that causes you to also relax as you learn. That made learning very easy. It kept my interest and actually made it sort of fun.

After 30 years having no dealings with academic studies whatsoever, I studied with Khan Academy for a few months and received an overall 82% on my TASC Test (which I discovered has been a replacement for the traditional G.E.D. of my generation). For math specifically, I received a 78%.

They have a fantastic thing going on there and I would recommend it to any and everyone! Highly effective.

It is great that the videos of the educational subjects are told with a superior approach and language. The choice of images and presentation is successful in terms of analysis of the subject. Offers in-depth examples.

Excellent free place to learn. I especially like the detailed videos; they look professional. I would like it if they had a Q&A or email function that let me talk to the instructors on the videos in real time.

They honestly are the reason I have been able to get through some of my harder classes.
Great style, fairly clear and much better organized than if I just went to their YouTube page.

Based on our experience, Khan Academy works well together with Beestar. My son started with Beestar's math program two years ago. He receives weekly math exercise for free. The questions are very attractive. Many of them come from real life to help students better understand math concepts. When sometimes he got confused about a concept, he would watch the video lesson on Khan Academy for in depth explanation.
Beestar is a user-friendly site. As a parent, I can monitor his progress online any time I want. As I have seen, his math performance is getting much better in the past two years. Now he's the top student at school. He likes to meet other competitive students from nationwide on Beestar. They even started an online math discusstion group. I feel happy for him and hope to see more miracles on him.

The people running Khan Academy all deserve medals. The website is easy to use, the team is quick to respond to questions, and the content of the lessons are excellent. A great supplementary tool for kids in High School, or a way to stay learning as an adult. There are classes for everyone, and the ease of use makes it super accessible.

If you ever have spare time and want to learn a thing or two about something maybe you never even thought you might be interested in, this is definitely the sight for you. The sight was established for those who could not somehow get an education (mostly due to financial issues). It is a great website and the best part is, it's FREE!

Excellent online educational source. This site has over 2 400 videos covering topics from arithmetic to physics, finance and history. It is beneficial to people of all ages. It could be used for high-school students or even adults that want to improve their skills, or for those oldies that want to refresh their memory. This site is highly recommended.

Very helpful. He explains the concepts very simply without losing the depth of the concepts. This has definitely helped me in college. Reviewing topics I hadn't mastered in previous classes has helped me with later classes which build off said topics.

A few years back, in one of my classrooms, I had students ranging in ability from doing math at the 2nd grade level to math at the 10th grade level. I had an hour a day to do math with all 4 groups (and these are guys with neurobehavioral disabilities so the one-on-one, immediate feedback time is important) so I needed to be creative and differentiate instruction using what websites were available back then in addition to a high school teacher's videos that I'd obtained somehow.

I WISH I had a website like Khan Academy available to me when I was teaching. Khan has tons of engaging lessons that I'm sure my boys with Aspergers would LOVE - much more so than hearing me everyday. The man behind this is pretty darn smart, and I think I'll watch some of his videos now rather than finishing an awful little history of the world book I have on my Kindle.

Forget tutoring websites, it's all here for free.

You might have read about Salman Khan in the news. The former hedge fund manager put a few math videos online to help tutor his little cousins. The videos were a hit amongst not just his cousins but thousands of others on YouTube. Since then, Khan has launched KhanAcademy.org and uploaded more than 2100 videos across a variety of subjects. The success of the site has attracted big attention from the likes of Bill Gates who has helped fund the academy.

Personally, if I had had a resource like this when I was a kid, I would have been in heaven. I loved learning on my own and hated learning in school. One of the most interesting ideas to come out of the Khan Academy is that some kids might be able to spend their "homework time" in the evenings watching videos on KhanAcademy.org and then during "school time" kids could do their homework and get help from teachers. This most certainly would work for autodidactic child, but potentially it could work for everyone as it could free up school time for more personal attention and less lecturing.

I'm a fan of the idea, and I hope it works. Oh, and check out some of the lectures. They're good. http://www.khanacademy.org/video/linear-algebra---eigenvectors-and-eigenspaces-for-a-3x3-matrix?playlist=Linear%20Algebra

It is not a solution designed for exams. Exam preparation is a whole different world. You need to consider that at Khan academy the information is not arranged in a way to fulfill all the criteria in SAT. It is helpful to illustrate some baffling points, especially in math, but one must not limit one's self to the content of Khan Academy.

By Shiori K.

There is an old adage in education , that 'Spaced' learning is more effective than 'Clumped' learning. Waiting for the next Mastery challenge teaches patience, allows you to practice more skills in the dashboard, so the mastery challenges have more to do assessment on, and as you note, ensure that the concepts are transferring from short-term, to long term memory in your brain.

By Grant H.

It does not help whatsoever. My son's grades in fact went down after his school enlisted him to participate in this program.
