So non-native means less than 50% or something? Also data is missing from many countries, it's just from one language school network. Cyprus and Israel are likely in Asian top 5, in Africa Namibia, Botswana, Zimbabwe or other formerly British countries could score higher than Tunisia.
Upon some more reflection, I'm inclined to agree with you. We've defeatured this quiz because of problems in the source data. No fault of yours @OnlyJon.
No problem. I've just done some editing and added some clarification to address some of the comments. Are there any other studies done to the scale of the EF EPI that I can base this quiz upon instead?
Apparently "non-native" doesn't means "non-official", since there are countries on this list that have English as an official language. So, what does "non-native" mean?
