Answer 1

Sololearn doesn't provide this information. A lot of users here want to get access to the public Sololearn API, but it is still not implemented.

Answer 2

I don't think the data is obtainable, without the use of SL's API, which, is not disclosed to public. Developers can get app download statistics from the GPlay Dev console, but again, those stats are most likely private to the devs.

I suggest sending a mail to the administrators to request such data. There are chances that they would be of help since you probably need it for academic purposes (?). Never hurts to try.

Answer 3

KrOW also wants to build something but he refused by sololearn team

Answer 4

If you just want a list of countries and not internal SoloLearn data, then you could look towards the International Standards Organization:
https://www.iso.org/iso-3166-country-codes.html
https://en.m.wikipedia.org/wiki/ISO_3166-1#Current_codes

The ISO site's downloads may be for-pay (not sure); when I captured the country codes for a project I wasn't required to pay (possible data source: United States Postal Service).

Basically, a public repository is the direction I'd look.
