Personalized learning: Students practice at their own pace, first filling in gaps in their understanding and then accelerating their learning.Nearly 20 million learners use Khan Academy every month in over 190 countries and over 40 languages. Their resources are being translated into more than 40 languages in addition to the Spanish, French, and Brazilian Portuguese versions of their site.

Millions of students from all over the world, each with their own unique story, learn at their own pace on Khan Academy every single day. They also offer free personalized SAT and LSAT practice in partnership with the College Board and the Law School Admission Council. Khan Academy provides teachers with data on how their students are doing so they can identify gaps in learning and provide tailored instruction. Their interactive practice problems, articles, and videos help students succeed in math, biology, chemistry, physics, history, economics, finance, grammar, and many other topics. However it took a very long time, and if just one mistake was made it would be nearly impossible to find it, since all the programs were just thousands of ones and zeroes.Khan Academy is on a mission to provide a free, world-class education for anyone, anywhere. People used to do programming only with machine language. The electric current can flow through all the gates that are on and whatever path the current takes makes it do something on the computer (ie make the screen light up a certain way, add some numbers, or send a message) The ones and zeros specify if certain “gates” in the hardware of the computer are either on or off. It basically looks like a bunch of ones and zeroes. When you run the code, what is actually happening is that the words you type are converted into binary code (also called machine language). However computers can’t understand words and number that are used in programming. So, computer programmers give the computer instructions on how to do that in their programs. People have to program it to respond to user interaction with a mouse and keyboard, show different things on the screen, and access the internet. Without being programmed, a computer would be useless. Programming is how you tell computers to do things.
