Final answer:
Khan Academy classes can be accessed from other countries unproblematically, with availability in multiple languages and subtitles. Physical location doesn't generally limit access to courses unless it's due to a country's specific internet accessibility regulations.
Step-by-step explanation:
Accessing Khan Academy classes from other countries can be done without much complication. Since Khan Academy is an online platform, physical location does not generally limit access to its courses. However, keep in mind that the ability to access the site may be impacted by the country's internet accessibility regulations. To access the classes, navigate to the Khan Academy website and select the course you'd like to enrol in. Indonesian and Spanish versions of Khan Academy are available for those who speak these languages, but you must access these through their respective websites. Language and subtitles in several different languages can also be chosen in the account settings page for greater accessibility.
