Hi, I was thinking of applying to the TU Wien Data Science master’s program, but the application process is causing me some confusion. They mention that the application should be sent via the national postal service, but the postal service here isn’t very reliable, so I don’t feel confident using it. Is there any alternative way to submit the application? Since they’ve specifically mentioned not to use courier services, I wanted to check if there are any other options.
