Yukon borders Alaska

I don't think Bahrain should count for "countries on the Arabian Peninsula" since it's an island

Usually "BH" is accepted for Belo Horizonte.

For the South African cities I think you need to define what you see as a city. Soshanguve is a township but is part of Pretoria and has been since at least 1994. Yet Soweto, which is a township of Johannesburg and has about 3 million residents, does not make the list. Same issue with Evaton, and most of the cities that form up the Ekurhuleni metro exceed 500 000 residents yet neither they nor Ekurhuleni make the list. If a South Africa cannot get 7 out of 7 what chance do other nationalities have?

The Euro is a South American currency.

Carstensz Pyramid, also known as Puncak Jaya is generally regarded as one of the 7 summits. It is in Indonesia, but I think should take the place of Mt. Wilhelm.

mt wilhelm is not the highest peak in oceania, it is puncak jaya. They are on the same island, so how could that be different continents. All of New Guinea is usually considered part of oceania not just the independent half
