The latest iteration of a study regarding the cost of student housing in Germany found, that rent prices for students have risen to a germany-wide average of 479€. Three years ago the average was just 391€. In Munich the average cost for student housing has risen to no less than 760€. This is more than double than the housing-cost covered by BAföG, a public program providing financial support to students from low-income families. [1]

Statistically, more than a third of students in Germany are at risk of poverty at the moment, meaning they have less than 60% of the country's mean income available. [2] [3]

Also with regards to Munich specifically, the number of designated student housing facilities has not grown significantly or even dropped over the past few years, while the number of students has been steadily increasing. This means that more and more students have to look for rooms in shared apartments on the city's highly competitive housing market. Statistically, these students are those that live close to the poverty line particularly often.

I realize that the cost of high-quality higher education in Germany is not as majorly fucked as for example in the USA, but still the financial burden on students is steadily increasing due to housing cost. How does this compare to where you're from? How is student housing organized in your city, how much does it cost relative to the mean income, and do you experience similar trends in your region?

I think many of us are students, or just like self-learning some topics for themselves, perhaps their work requires studying — I think it might be interesting to collect a few tips we have experience with on how to do it efficiently.

I would start with probably one of the best tools in this category that I think are still underutilized by many: spaced-repetition software. Perhaps more people might be familiar with the concept from language learning with word cards, but the base idea is that reinforcing some knowledge at increasing intervals will effectively make you remember it ’forever’. A final selling point on this topic: it only requires 10 minutes out of your entire life to remember a fact for basically forever with instant recall - that’s a very good use of one’s time in my opinion. For more information on it here is a great article.
(It’s talking about Anki, a notable spaced repetition program that is free and open-source (the ios client is paid though, as this is the only income source of the maintainer, but you could just use the web interface as well. Not affiliated))
