Hello Gowri,

I think you'll be coming around in the 3rd round of counselling. Most probably you won't be getting a seat in top colleges under general vategory but you can get seats in community based cutoff category. I will attach a link for you for to check which round you'll be coming and what are opening and closing ranks for the courses.
