Hello Abhishek, 

SSCBS is a college affliated to Delhi University, Delhi. Admission for any of the courses in Du is on the basis of merit, and for programmes like BMS, BBA etc, it is through an entrance exam called DU JAT which is conducted by DU as well. DU JAT (Delhi University Joint Admission Test) 2019 will be scheduled for June 22, 2019. The online application form for which will be available on the official website of Delhi University from May 15, 2019. The date of examination is scheduled to be June 22, 2019.

As for Panjab University, or PU, it conducts PU-CET to grant eligible candidates admissions into the UG and PG courses offered by the university. The Online Application Form and Prospectus for the PU-CET will be made available from 5th April 2019. Also, Panjab University has rescheduled the date of entrance test for PU-CET (UG) Entrance Test-2019 i.e. from 28th April 2019 to 30th April 2019. 

Before applying, make sure to go through the eligibility criteria carefully. If candidates submit the application form despite being ineligible for the entrance examination, their application form will be cancelled by the conducting authority. 

I hope this helps.
