Yes, it is possible to apply for a higher semester. The application procedure is exactly the same as for the first semester. You can also apply for the summer semester.

The application period (usually December 1 to February 15) can be found here:

Please note: For a successful application you must meet all the same admission criteria as for the first semester! Additionally, if you apply a higher semester, you must also prove that you have the level of knowledge from the first semester. This means that you must provide evidence of at least 16 creditable CP! Only then is there a chance of being accepted into the second semester.
