Well they taught us pinyin, but I was and am pretty dumb, so no HSK 3 for me.
Same with for all the overseas born Chinese here in Germany I know and in extent Europe (France, Italy, Germany, Spain) as a whole.
There is this split, one part of the family raised their children purly "european" basically prototype bobalib in result they speak shitty mandarin and only marginally less shittier dialect, the other half educated their children in mandarin and dialect well and the mother tongue of the emigration country was, more or less, learnt via kindergarten/school.
Also, as
@Tse mentioned for SG, here in Europe too, if you speak Chinese in public, you get eerily stared by white aborignies.
