But.. I couldn't do it

The first day in IIT-2A section, met some new friends and some of my old friends too. Sagar, He was in the top section IIT-2*. That day we had an exam in “Surface Tension”. I didn’t understand the topic at all. The lecturer was Y.M. Sir former professor from IIT-Madras. His level of teaching was very high for guys like me. I had Arihant series book in my hand. I couldn’t understand a bit. Everybody near me were clarifying their doubts with the lecturers. I felt bad, very bad. That I couldn’t understand what everybody did. I felt like crying. It was a new atmosphere for me. New campus. Many new friends. And most difficult topic to study (difficult for me at least). Somewhere in my mind told me that I do not belong there. Something should be done to save my life. What should I do? I came away from my home(in this context it is Sindhu campus..haha..). I had many friends there. Many who were not geniuses. I felt inferior here. I decided to go back. Back to Sindhu campus. Back to AIEEE section. Back to nikhil and all my old friends. I was almost crying by that time. I went to the In-charge and asked him the permission to leave to sindhu campus. First , he said no. I cried. Then he said yes and arranged a car to take my luggage back. I was back to Sindhu.
All the droppers (from IIT) were in two sections. ID-1 and ID-2. ID stands for IIT Droppers. I was in ID-2. Late dropper. In the IIT screening test three guys who scored more than me had also dropped from IIT. Ashok was one of them.
