This will be the registration cum application process. You will have toregister online at their official website and once you register you will be given a random 10 digit number which will be used during tie breaking situations. The admissions will be based on the marks scired in your 10+2. After the registration, you will be allotted a Facilitation centre and on the allotted date you need to get your documents verified. Post that the merit list will be released. And you will have to participate in online choice filling and confirming of the seat.
