How old are you?
Could you go to university and are eligable for Bafög?
Do have a support network at home?
I'm 35. I could theoretically go to university. But I would first have to study one year to pass the university entrance exam. In any case, I would rather avoid it. If university were a realistic option for me, I probably wouldn't be in the situation I am today.
University of the People doesn't have an entrance exam, and it's zero tuition.
