COO Ginny Lee's salary was $700,000. Khan Academy's website aims to provide a personalized learning experience, mainly built on the videos which are hosted on YouTube. The website is meant to be used as a supplement to its videos, because it includes other features such as progress tracking, practice exercises, and teaching tools. The material can also be accessed through mobile applications. The videos display a recording of drawings on an electronic blackboard, which are similar to the style of a teacher giving a lecture. The narrator describes each drawing and how they relate to the material being taught. Non-profit groups have distributed offline versions of the videos to rural areas in Asia, Latin America, and Africa. Videos range from all subjects covered in school and for all grades from kindergarten up through high school. The Khan Academy website also hosts content from educational YouTube channels and organizations such as Crash Course and the Museum of Modern Art. It also provides online courses for preparing for standardized tests, including the SAT and MCAT and released LSAT preparation lessons in 2018.Khan Academy has also supported Code.org’s Hour of Code, providing coding lessons on its website. In July 2017, Khan Academy became the official practice partner for the College Board's Advanced Placement. Khan Academy videos have been translated into several languages, with close to 20,000 subtitle translations available. These translations are mainly volunteer-driven with help from international partnerships. The Khan Academy platform is fully available in English (en), Bangla (bn), Bulgarian (bg), Chinese (zh), French (fr), German (de), Georgian (ka), Norwegian (nb), Polish (pl) Portuguese (pt), Spanish (es), Serbian (sr), Turkish (tr) and Uzbek (uz), and partially available in 28 other languages. Since 2015, Khan Academy has been the official SAT practicing website. According to reports, studying for the SAT for 20 hours on Khan Academy is associated with a 115-point average score increase. Many book exercises select questions from the Khan Academy site to be published. In 2015, Khan Academy teamed up with Pixar to create a new course called Pixar in a Box, which teaches how skills learned in school help the creators at Pixar. In 2018, Khan Academy created an application called Khan Academy Kids. It is for young two-year-old to six-year-old children to learn basic skills (primarily mathematics and language arts) before progressing to grade school. Khan Academy has been criticized because its creator, Salman Khan, lacks a formal background or qualifications in pedagogy.
