1. 5/5Great app but a minor complaint

   This is a great application, and it costs you absolutely nothing. However, if you are going to delve into Multivariable Calculus or other subjects that require you to use “special” characters such as Euler’s number e, which they use often, to enter your answers to the posed problems in the practice, then good luck trying to enter it. For instance, if you are asked to find the gradient of a function f(x y z) = y^2*z +e^x Then it will be . There is no button for the number e to be found, so how can one enter the answer? You can’t! That is only one example of something that needs to be addressed. Your answer is marked as completely incorrect all because because they didn’t provide you with the means to enter the correct answer correctly. There is no way to simply type the number e on the provided keyboard that pops up. I searched and searched their help files, but that was to no avail. I tried to copy and paste it from another keyboard, and that proved futile as well. This is the ONLY reason that I didn’t give this five stars!! There is a lot that one can learn from Khan Academy, and please get me wrong. I love this app and have used it for years. I have donated to their funding drives, and if you use it, then you should consider doing so.

2. 5/5👍W Khan Academy

   Khan academy was the only educational resource that I found tremendously helpful. Every single lesson was easy to understand and helped you figure things out. The topics were articulated beautifully, the reading sections were great and for some reason I can’t describe explained as well as a person talking to you. The dark mode that’s being implemented right now is also really nice. It’s easy on the eyes and everything looks “smooth” and good. Another good point is when your reading information from the “articles” there sections that you can tap if you don’t understand, these are really helpful. What’s even better is when your solving a problem and you get it wrong, the app shows you step by step how to solve it. This sets khan academy miles apart from other learning platforms. The fact that this is a FREE learning application is 100% better than 90% of the PAID learning apps/tools is a steal. I fully suggest that everyone donates to support this app. And if your reading wondering if you should download it, I strongly suggest you to do so. This app is just ✨the best free learning tool ever✨and I’d go as far to say it competes with paid platforms as well. It’s just easily one of the top places to learn. I can’t believe all of it is free, so khan academy thank you for the free learning.

3. 5/5Incredible… just incredible.

   Khan Academy is hands-down one of the best free learning resources out there. Whether you’re brushing up on algebra, diving into world history, or exploring computer science for the first time, this platform makes it all feel approachable and surprisingly enjoyable. The lessons are short, clear, and straight to the point — no fluff, no unnecessary jargon, just good teaching. What really stands out is how well it caters to all kinds of learners. Struggling with a topic? You can rewatch videos, practice problems at your own pace, and actually master the material before moving on. The mastery-based approach is a total game-changer — it builds confidence instead of frustration. And honestly, the fact that all of this is completely free is incredible. Khan Academy could easily charge for this kind of content and still have loyal users, but instead, they’ve stayed true to their mission of providing a world-class education to anyone, anywhere. It’s education with heart — something that’s rare these days. Teachers love it, parents swear by it, and students (even the ones who “hate math”) often end up admitting it actually makes learning kind of fun. Bottom line? Khan Academy isn’t just a website — it’s a revolution in learning. If you’ve never tried it, you’re missing out on one of the best tools for personal growth and education ever created.

4. 5/5Great app but few suggestions

   This is an amazing app and I really can’t find too many things wrong with it but I do have a few suggestions. There isn’t really much space to draw on the drawing tool if you can’t write small. Maybe you can make it so there is more space on the drawing tool and you can scroll down to get even more space. Another suggestion I have is to add reading lessons. If you don’t know what to put on reading you can make us read a book and tell us questions about it later. You can also make us try to spell words and sound them out. For example if the word was awesome the answer would be awe-some, I think, I’m not good a reading or sounding out words. For the videos that teach us how to do the upcoming tests you can tell us strategies on how to remember what happens in the book. You can also tell us how to sound out words and figure out how to spell words by sounding them out. You can also tell us what kind of information to put into our writing when where writing about the book. Ok I know I said I had no problems with this app but I do have one. If you redo a lesson and get a score lower then the first time you did it, it changes your score to the lower score instead of keeping it the highest score. Sorry if that explanation was bad I’m only nine years old but I was trying to say, if you redo a lesson but get 3 out of 5 answers right and the first time you did it you got 4 out of 5 of the answers right your answer still changes to getting 3 out of 5 answers right. I don’t really like that feature and I don’t think others like it too. Other then that problem this app is amazing! Please don’t stop working on it!

5. 5/5👎👎

   There are mistakes in some videos. Sometimes he writes down a different number without explaining why he changed it. There is one example in one format, and all the questions in the practice part are in a different format and you have to learn how to solve it yourself. I have spent over an hour in one practice section because even though I did all the math correct, the way I was typing it into my calculator was missing parenthesis that in the explanation didn’t even say to do so. Basically, I was getting some questions right and some questions wrong even though I did all the math correctly. The explanation misinformed me by forgetting things like parenthesis that will make you end up with a completely different answer. It would be nice if there was a way to restart a unit test in the middle of doing it. To start from the beginning again would be nice because I have spent the last 6 hours redoing one unit, I’ve had to redo the unit test over 10 times, and each time I make a mistake, I hav to finish all the other questions correctly before having to restart again. Overall, it’s annoying and a waste of my time.
