Just an advice
Hi, I wanna give advice to juniors (which I felt I needed very much back in time).
So, the *JEE* exam is finally over. I know I am posting this very late :) . Many students may did very well and got their dream college/branch. But some folks, who worked really really hard, but didn't get their deserved seat. There could be multiple reasons (some of which aren't even in control of us). I want to say YOU DID REALLY REALLY WELL. Be proud of yourself for putting all the efforts in your attempt.
Stop lamenting over this. Don't feel that the hard work you did was all in vain. NO, NOT AT ALL. The knowledge and most important "the experience" you gained will definitely carry forward in your career. You need to accept the situation and take decisions accordingly.
Now, coming to the decision of branch vs college. There will be many ppl who will just conclude this by saying, 'give priority to college tag, that's it'. I did find many many ppl like that during my time. But I listened to myself. I'd say, instead of listening to others opinions, you need to decide for yourself, what is the best option available to me, rn. What do you REALLY LIKE to do. Research for yourself, scrap sites data...just don't follow anyone blindly. It's your life and you alone need to take decision for it.
Either it's the decision of branch vs college, or even, drop or partial drop. Just decide for yourself and go for it. In the end, it's only you.
All the best!!
