There is very little chance to get your branch upgraded to any department. Even if you manage to score more than 80% then also you will not be able to get a seat in your desired branch as they might show there is no vacancy in that branch.
To get your branch upgraded from EEE you either need to have very good connections in GGSIPU or you need to lend some extra money to the college to upgrade your branch. Without which you won't have any chances to upgrade even if your score is more than 80% marks in the first semester.
