Other options for financing your studies
Some banks offer loans specifically designed for students. Probably the best known is the KfW student loan. A student loan must be reimbursed plus interest so that it adds up to a significant amount. However, as terms and conditions of suppliers can considerably vary from one another, you are advised to consult an expert and compare different offers first.
Students in a higher semester can take out an educational loan with the federal government. This type of financial support is a low-interest loan that you can apply for regardless of your income. However, the amount needs to be repaid in full and including interest.
