Hello Pratiksha,

Generally till last year admission was been given based on IPU-CET exams conducted by the university. Last year they changed the norms and started giving admissions based on CAT scores as well. As per the circular on the IPU website, they will accept CAT scores for the MBA programme for the academic session of 2019-20.

However, if the MBA seats remain vacant till 31st July 2019 then IPU will take admission through CMAT. 
So, keep your fingers crossed

Also, do check their website and the circular.

Hope this help
