Sourabh,
You got it right. Just stop worrying and start enjoying your engineering days. Have fun and keep an eye on the industry (Keep visiting, interacting with CEans and you won't have to do anything special to know what's happening around).
As I said, concentrate on your engineering subjects. Any interviewer will want to know if you really know what you've studied for past four years (during entry level interview). So you can't afford to go wrong with that.
Summer trainings are (I guess) at the end of third year (correct me if I'm wrong). CEans have a track record of helping CEans with summer trainings. Why worry? You have CE to take care of all your problems.
Have a great time here & wish you all the best.
