Because of the still active COVID-19 pandemic the teachings still mostly take place in a digital form at the colleges and universities of the state, which is justified due to the current pandemic situation. However, these circumstances are an immense burden for the students as well as the teaching staff. The digital tools provided by the colleges and universities might work to some degree (there might be exceptions) seeing that we are currently in the fourth semester that has been compromised by the pandemic. Furthermore, you could think the students are now familiar with the situation and accustomed to the digital teachings and thus ceasing the supporting regulations is justified.
With this reasoning the individual circumstance of each student is disregarded. The influences on each individual student may include but are not limited to:

• Bad internet connection: low bandwidth and connection break-offs are not only a problem for the teaching staff but for the students as well. The student can’t follow the contents of the lecture. In case of a connection break-off during an exam the student’s ability to properly display their knowledge is hindered immensely. So far that a failed attempt could be the result. Connection break-offs are not isolated cases in Germany due to its failed promises of expanding the bandwidth on a national scale. Telecommunications from the 50s are still in use without any kind of modernization. It does not come with surprise that Germany only manages to reach the 25th place in the State of the Internet Ranking (Quelle). An (unfortunately) still up-to-date video of the ZDF Neo Magazin Royale depicts these deficits regarding digitalization among other things. (Link)

• Psychological health problems: Students are under a lot of stress. This is well known certainty. A report by Deutschlandfunk form 2019 (Link) shows that this issue has been know before limitations of the pandemic set in. Social isolation, lacking separation of work space and living space and missing earnings due to weggefallene side jobs are only adding to this issue. Another foothold for the students to adapt to the pressure of their studies that ceased to exist is the contact to other students. Visiting a Christmas market and talking about your hobbies instead of your studies? Not happening. After a day of lectures students are glad to be able to shut their computer off and don’t spend time online with other students. That the online studies cause damage to the mental health is shown by a poll done by the TK (Link). Note: if you don’t feel well and don’t know what to do anymore, please look for help. The crisis line (+44116123) is available 24h a day, seven days a week and even available online: LINK (for other languages than English: LINK)

• Layout conditions: A small room to set up an office space is not only convenient for tax returns but also helps to separation between work life and private life. If you live alone or with other people this separation might not be possible due to financial circumstances. This leads as stated above to even more stress on one’s mental health. Separation between work and private life is often not possible because of online studies.

• Financial circumstances: Going to college or university is a conscious decision of each individual to get a non-paid education but for most students their studies are their way to achieve their first educational degree. Most students are full time students at the colleges and universities of the state and because their studies are non-paid these students have to fund their living expenses. If there are no savings, the family can’t support a student nor are they receiving a scholarship the only option to fund themselves is to either receive social benefits (BAföG) or take on a side job. Taking on a side job can often times lead to exceeding the regular period of study because of the required time that can not be invested into studying. Many side jobs of the students, especially those in the restaurant business or in the bypass of production in industries in the summer, ceased to exist due to the pandemic. This is shown in a report by the BR(Link). The unfortunate financial situation is often times attended by the absence of technical equipment that is needed to participate in online lectures.

The reasons above are far from complete yet at least one of them if not more does apply to almost every student. The colleges and universities might have adjusted to the digital teachings though the disadvantages of exactly these digital teaching do still apply for the students.
