Hi Ayush, one should have completed his 10th and 12th from one of the following, 

1) Karnataka PUC 

2) ISC 

3) CBSE 

4) NIOS 

5) IGCSE 

6) IB 

Maths is not a compulsory subject required. And yes there is chances to get admissions for the scores you have obtained as the minimum mark is to pass 50% in both 10th and 12th. One needs to clear their entrance exam upon which admission is obtained.
