I'm a native English speaker, so for kicks I just took the Migros online placement test. Apparently my English has progressed to the point that I can start at level B2.

There were also noticeable errors in some of the questions, and places where the "correct" answer required phrasing that I don't think a speaker of British or American English would use. (I'm afraid I don't know the peculiarities of Indian English.)

Hopefully they do a bit better with the local languages.
