Great! One last question though: the interface seems to have been designed for adults; I have to choose whether the application is for myself, or for a 13-17 years old. I'm both, what should I check?

Exact same problem here. This seems to be specific of SSC applicants. Also got the mail.

That's a shame, I didn't think there were companies as big as Brother that would just sell their products without support after it. The product works well. But no proper driver. This is their answer: https://help.brother-usa.com/app/answers/detail/a_id/171587?R3ModelID=MFC9330CDW&_ga=2.74734098.1212927454.1628149942-372246198.1628149942. I wouldn't have thought they would recommend the wobbly solution I use to all users... but they did without even blinking. "Brother: at your side."
