If you think that you can afford to finance your studies, than a Blocked Account or known in German as Sperrkonto is required.

It is required to have a minimum of 8040 Euros in your blocked account in one of the German banks and the maximum that you can withdraw is 670 Euro per month. (for more information about the exact amount – go to the Embassies websites). It is required to make this change so you will not be facing any problem in the future.
