On January 12, 2016, Microsoft stopped providing security updates for Internet Explorer 10. Khan Academy has begun to phase out support for IE 10. This means that in addition to the security risk of continuing to use IE 10 or earlier versions, chances are increased that your user experience of Khan Academy will be less ideal.
To ensure the best possible user experience with Khan Academy, please use Chrome or Firefox browsers, or ensure that your Internet Explorer is up-to-date.
