Hello, katyanick12. Your question is about KA or this E-Learning platform called Unacademy? If it's the latter, I'm afraid I won't be able to help you much. KA is structured differently depending the language you have chosen where English is the most developed one. I've heard that Indian, Portuguese and Spanish (in that order) are also good. As far as I'm concerned, they only follow American standards or Indian standards (depending on the language). KA is also free, donations are voluntary and are what make this site provide free world-class education. 

International schools standards do typically follow GCSE, IGCSE, A-levels or IB (International Baccaleurate). Here a link with more information. 

Unacademy seems like a good option. Doesn't appear to be a scam and I don't know how fees go as I've never used it. Apparently follows the Indian curriculum. I guess that if you're paying they have a support staff. 

(Opinion that is not relevant to this conversation): Sal Khan was one of the first people uploading educational videos to YT (not the first one, I know of people that did before him). Even so, he created along all the people that have worked/work both payed and voluntarily to create this incredible and life-changing website. I just want to show my uncomfortability with these type of websites. For me, appear like Alibaba. Or even brand-telephones different from Apple, (I do have a Xiaomin tho 😢😆). There's obviously a niche there and KA by then didn't offer possibilities to the Indian curriculum. Perfect copies, no originality. 

Again, don't read this last paragraph. The conclusion is to google and contact support.

Hi katyanick12,

Most of the content on the English version of the site is mapped to the U.S. Common Core standards. You can learn more about what these standards cover here: http://www.corestandards.org/

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