Hi Vivek,

Unfortunately the Khan for Educators giveaway is limited to U.S. residents only due to legal reasons (there are a lot of different complex rules and regulations for international contests and giveaways).

However, if you live outside of the U.S., you're still able to access and complete the Khan for Educators course for free! Additionally, you can access an online version of the Khan Academy Refresh cards here.

I hope this helps! Please let me know if you have any additional questions!
