As the 5th amendment to the APB has been in force since October 2015, the following applies with regard to a PO change:
As long as you do not submit an application, you will remain in the old examination regulations. If you want to change to the new examination regulations, you must apply for this. Please use our form for this purpose.
Once the change of examination regulations has been carried out on the basis of your application, you can no longer switch back to the old PO.
Please also note the equivalence tables.
