Hello Zainab,

To get admission in the colleges affiliated to GGSIPU you need to clear IPU CET which is conducted every year in the month of May for various programmes.

After clearing the CET the GGSIPU starts the counselling process where first you have to register yourself and then can select the colleges depending upon their rank and you choice. You can not separately apply in the College only through GGSIPU counselling you can get seat in the affiliated colleges.

To know more about the IPUCET you can go to the below mentioned link to get in touch and stay updated to the relevant information
