I also took it in Hamburg and the people in charge told us, that the results will be online end of august/start of september (with the login data from the voucher). Letters are send out in october.
While we are at that topic: they want everything so miniscule precise (like they had a whiteboard with the alphabet and numbers on how we have to write) and the test is scanned automatically - why does it take 2 months to get our results? Not the letters ofc, I get that that may take a while for all students.
