What happens at the first day in AIIMS Delhi for an MBBS?

I have a friend from AIIMS, New Delhi, and here are some snippets of his experience from his initial days. 

• The first day he got to know that he will be studying at AIIMS Delhi was quite overwhelming for him. He got many calls from his family and friends. He also received a video call from four of his seniors who seemed scary at that time but after his freshers, they will become his favorite seniors.
• When he reached the AIIMS campus, the first thing that he wanted to do was stand in front of the garden which he had thought of for about two years and get a picture clicked. But he ended up getting confused between gate number one and gate number two and entered through gate 3. It’s better if you know a few seniors beforehand, they might take you to the hostel and your room, and then it becomes an interactive experience.
• On the first day of CREST, his parents made sure he was settled in the hostel. Then the first thing of the day was the director‘s address in the Dr. Ramalinga Swamy board room. As the day progressed, he got to meet various people. Some of them became his best friends in a month. After this, he was taken to the campus and the hospital. He also visited CRHSP Ballabgarh the next day which is the sub-district Hospital under AIIMS where students are posted during their third years and internships. They also visited a PHC in Chains which is a village posting after the internship.

This was his initial experience at AIIMS.
