I was in this state before and i can feel you all.
Just remember that Jee preparation itself is a wonderfull expirience.
Life at iit goes in recalling these days and sharing these memories. So treasure it now that you have it.
These days its the skill thats more imp than degree/college. I am sure by now you know that there are plenty of colleges other than iits where life is dope and exposure too. So not wasting our time to remind you that.
Good luck guys.
And all the best for JEE results!
