Hello Aspirant

You should go for DTU EE as DTU is known for it's core branches. On top of that you would have plenty of time to get involved in extra curricular activities and you can also focus on coding if you want to, whereas in NSUT the work load is comparatively more.

Now coming to the upgradation part so after JAC counselling the upgradation of branch happens at the end of 2nd semester which is totally based upon your JEE Rank, your 1st year score doesn't matter.

Hope this helps.
