I have been allotted Instrumentation in IITKGP in 1st round of counselling and I am the branch opener as per Jossa OR CR. My next higher choice is EE in the same Institute. May l get it in the subsequent rounds?

Dear student,

First of all your must mention your jee advanced rank along with your category.
As you haven't mentioned it so, I am assuming that you belong from general category.

Now, first of all congratulations that you got instrumentation engineering in IIT KGP and your rank is the opening rank of this branch.
Now as your rank was the opening rank, ans you got instrumentation engineering in 1st round then your general rank must be around 1500.

Now as your general rank is 1500 ( assumed ), then for getting electrical engineering in the same college you have to use slide option. Now as per seeing the last year cutoff trends - the cutoff of electrical engineering branch is lower than 1500 general rank. So, there is no sure saying that you will get ee or not, because for getting sure seat in ee your rank must be under 1100. You may or may not get seat in ee in further rounds.
And also the actual results will be shown in josaa further rounds counseling.
So, Wait for next rounds.
