Dear Student,

After first round of counselling you will get a chance to change your preference that you have saved in the first round.

As you want the 6th position college so you can put that college in the 1 place so the chance will increase to get the seat if any left because most of the seats are already filled in the first round.

You can do whatever you want in your list when the window will open to reorder but remember that don't exclude the college you got in the first round.

Good Luck :)
