All entrance exams are over, you will have to apply next year.

Yes, else how would the colleges know of your application.

I feel that it all depends on how well you prepare yourself for the Eligibility Testing. Streams may count marginally. So, an exhaustive preparation will surely yield success.

Please clarify your question. Why do you want to change your stream if you have already planned to pursue UG in commerce?

Yes, you will get it in 2nd or 3rd round.
All the best.

Hi Pranav,

To pursue two courses at the same time, the mode should differ i.e. you can pursue one course from a regular mode and the other through the distance mode.

Normal course is four years and SS is five year where you have 1 year of internship like practical work. Which is different from labs in normal course.
