Khan Academy: Calculus 1 App Reviews

And its free! Thank you so much!

Great initiative. But, the videos dont have audio.

downloaded most of the videos and learned a lot! everything is explained clearly and in steps slowly so you never get lost. handwriting is a little messy sometimes but a really good job considering its all drawn from a mouse. thanks for making these.

This is an excellent tutorial that helped me A LOT! Truly amazing!! Thank you so much for your work and effort.

This is a very helpful program!! The guy teaches better than my teacher!

Super useful app especially for first year calculus! Id buy it even if it cost 5$! Instructor is very easy to listen to and explains very well! :)

Thanks sooo much! Im in gr11 tryin to prep for calc in gr 2 and even i understood them! Keep on doing what ur doing! :)

Cant see the video. Can hear it though.

I love this app and would love to have it on my droid x

Its so much easier than anything that the teacher tries to explain. I love it!!!

Khan Academy won the Google award the other day and now expanding. Congrats for great tutorials.

These tutorials explained the work so well! My teacher had me lost at the first word but these are usable for visual and audible learners. Thanks so much!

A little rough in the presentation ("my pen has stopped working!") but that actually adds to its genuineness, like youre actually sitting in the classroom. Actually learning calculus and enjoying it! Thanks for a great app.

I would have rated this probably 5 stars if it didnt crash every other time I open it

2100+ videos and everyone of them is insightful and extremely helpful. His amazing use of colors really helps separate the points hes making. Great information, it will help you pass Calculus

This is like a mini lecture that u can refer too anytime. If I had a problem with related rates I can just go to those videos and it helps a lot. the guy who works the problem explains every step, which is helpful cause my teacher usually skips a bunch of steps and I have no idea how she got there so this app helps. Im taking cal bc now but anyone taking cal should have this either in high school or college.

In 15th video at 4:00 answer should be 6+h. Not 6+ h2. Overall great videos.

Its VERY USEFUL! It makes calculus much easier then everybody has advertised! Keep the apps coming!

This is very easy to understand. It made the scary part of maths interesting.

Just wanted to mention that you should look out for a factoring error in the last limits example, he added instead of multiplied jfyi!
