If I get 2nd/3rd option of my choices in the 1st round but I go for upgradation & then in 2nd/3rd round if I do not get my 1st option,
Hi Aspirant
Since you have not specified the particular competitive examination or counseling I will write about what generally happens in other counseling.
If a candidate goes for float option that is upgradation one either gets the same option that one got in the previous rounds or one gets an option that is higher on the priority list.
Hope this helps and All the Best.
