Most major banking intuitions offer student loans at attractive interest rates. Interest rates may decrease for consecutive years of study. Normally bank loans cover the duration of study and are repaid once you start working or once you have graduated. Some banks offer a grace period to students who are completing internships, articles or community service. In most instances you are required to repay the interest while still studying. Sometimes surety / security is required, which means that a relative, friend or sponsor must guarantee to repay the loan if you fail to do so.
