Hi there, these problems can be addressed at later stages. It is a minor issue that university will look into. If you fulfill the eligiblity conditions for the program, you will get admission. Hope this helps. Good Luck

No need to worry. Because you will not get to select PCM as the subjects now. When you will appear for the exam at the center allotted by them, there will be option on the computer screen to select the subjects you wants to answer the questions of.

So, you are not required to select the subjects now (before appearing for the exam).
