Read every instruction twice: once for the first time you see it and before the actual use.
Sometimes I hate this system of "independence", which is very difficult to get used to.
I got the results of my electronic exam in Accounting, for which errors I would like to have a look. Below the results was written the date and the time of the possibility to check what had I done wrong (Einsichtnahme). However, I didn't click on the 'directions to this Einsichtnahme' and as it turned out, it was necessary to enter it until Saturday 12:00. Well, thought I yesterday at midnight, I write them an e-mail, but I'll go tomorrow to 8 o'clock, to the beginning. On the halfway I'm getting the answer that I am a very bad girl that I have written them too late but it's still possible to get an appointment (Termin) at 9:30.
Of course I am very happy that I have still got this possibility to take a look at my exam.
I think they also could send additional information about these examinations and such people like me could avoid problems like that. But probably I just want too much.
