I have filled my IPU CET form but there wasn't any choice for exam centres, I tried contacting the exam authority but nobody replied.

Hello,

Guru Gobind Singh Indraprastha University (GGSIPU) will conduct the IPU CET exam except for B.Tech for admissions to various courses offered by the colleges affiliated to it.

The admissions to B.Tech courses will be done on the basis of the JEE Mains scores and the B.Tech candidates will have to register for the counselling.

As for your question, if you have filled the form for B.Tech. other than Biotechnology then you won't be allotted an examination centre as the admissions will be done through JEE Mains.
