This is awesome! I can't believe that this could help me a lot! I just installed it because I'm finding my way to review for our geometry subject because we're having our periodical exam tomorrow and I don't even understand my teacher. But with this! Everything was cleared, good explanations and very understandable, and the also give some exercises and here. everything is solved! Thank you! Love you guys! especially the for guy is teaching in geometry. Because of you, I have the confidence to pass the exam
I'm taking chem 1 in college and my teacher is so bad. So lucky I thought to look at khan Academy! Everything makes a lot more sense and they provide lots of examples which is really helpful.
Love Khan and have been tracking the development of this online university for years now. Please fix the drop down menus in the skills tests. They do not work on my Android phone. Other than that it is truly wonderful.
I can't find where to ask questions relating to the videos. On website its more interactive because we can ask questions and also view and answer other people questions. Plus on our dashbord page we can view our activities, badges, discussions, etc. I can't find these options on the app. Please help
I'm a first year college student, who was struggling (failing) in biology and this really helped me out. The videos explain the complicated processes in a way that is very understandable, that I just couldn't grasp in class. Very happy that it's free too. Thank you!
Having trouble remembering what you learned in Math today? No problem heres how to do EVERYTHING (edited Tuesday, October 8th) I still love this app, but when I save and download videos it, it saves the videos in the order that I downloaded them which can get unorganized. Could you please add an portion to save them in folders??? Thank you!
Easy learning with every subject,young and older,Mb storage less than other large storage apps.. can't go wrong with this app..two thumbs up!
Awesome explanation of physics ,chemistry,biology,history,mathematics. My son has found this app very interesting and has no need for tution Khan Academy haz provide us free which is a very good social work but somewhere I know that the guy is making a huge profit.
It's boring but I have to do it for homework. I like the avatars though. It's very educational too. It could be a little hard.
This is an out standing work, and world class educational resource, which enables learners who can access the internet a free a to z education. This is the best I have ever seen. Thank you Mr Sal Khan and his teem, as well as the other helpers, to mention few the MIT university, google, Mr Bill Gates, the other doners. I hope the world will recognize you, and will appreciate your good deed's. Thank you all.
I loved online courses in college. Khan Academy's courses are structured masterfully. They seriously improved my comprehension of calculus and other difficult subjects. Bravo!
Great app and fantastic service! Please add possibility to save articles and quizzes for offline use. And please add a button to download whole topic at once.
It is very educational because it helps me learn what ever I'm learning in school and it keeps me up to date with school. I highly recommend this app if you are trying to go to college.
If the subjects are what you want it might be worth a look. After reading the reviews, I was disappointed. Uninstalling.
Good work but its less interactive as compared to desktop version as am unable to ask questions and there is no notification panel there
Won't let me do the exercises its keeps on saying unexpected error or try again when i try to open or do an execrise
This app is based on the heavy work of a great and very powerful team. Despite of a small bug on marking videos as watched after viewing, the equation editor and exercises are very nice and easy to use and understand.
I very much like this app and a special thanks to its developer. Amazing effort of a team.
SOOOOOO helpful , it boosts math , computing,the human system and biollagy . if i could i would rate 100 ★'s
The idea is that people can requst and ask for things they might want to learn... and one where they can vote on ideas
It's great it helps me understand my math better and help me with my GED subjects THANK U FOR ALL THE HELP
Amazing just started. Excellent explain. Sometimes would be nice to ask questions to clarify my right or wrong underestanding. Best up to self educate. Thanks!
IV been using this site for over 3 years now and it's gotten me As in all my college math, biology, and chemistry. This is one of the best ideas on the planet. Free in-depth information in an easy to understand format. I love it.
This is the best learning app I have seen. It is also free, unlike Byjus learning app, which is only for 15 days.
If there is an email I could send pictures too, there are a couple of exercises where there aren't options to choose an answer from in questions and where the "see how we answered it" section doesn't match the question.
I love it so much.. I wanna join you all in future.. I wanna make learning an awesome experience. Thank you for making science so interesting.. Thanks a lot KHAN ACADEMY. Mr. Sal , I'm a true fan of yours !
Zra de rala khoshala Khu taso pa reshta da khan nom ochat ao dher waprrakaw dunya ta !
I like it. It helps me with my math skills. It lets me work on my math when not in school.
My professor at MDC sucks, Kahn Academy has saved my little PreNursing butt. It breaks down Chemistry into a chewable, and easy to understand manner.
Why is this app not loading up the articles? Any articles that I've tried reading says that it can't load up?? Fix it..
The videos and contents are fantastic. Keep it up. Any number of praises for you wouldn't be enough. Not everyone can afford to pay for education. Great work Mr. Khan
No words to describe this App..Simply Brilliant..You all should've try it once and you never gonaa be delete it..
If you get a practice question wrong. It crashes when you try to view the answer.
I love it, it really helps me study. I would really like it, if there was an option to somehow 'favourite' specific topic and have easier access to them.
This is great as u can learn many things for free. Thank u very much. U r doing a great job
I hope there is an offline article menu, so we can view the article offline. And I think when we select the link in the app, there should be a menu to open the link in the app itself.
Khan Academy is a great app for anyone who needs help in any subject. If you use this app im sure you will excel in life:)
The App is just awesome!!! I love it.
Get this application if you wanna learn.
I wish I would have found this app long time ago. I just love it. It makes everything so easy to understand and apply.
