Sure, here are a few pics personally clicked by my cousin who was a student at AIIMS Delhi.

As a resident of AIIMS Delhi hostels, you are completely free to customize your room as per your needs. Many of my friends there got their rooms painted and even brought their own AC, microwave, and refrigerator.

My friend shared her first-day experience at AIIMS Delhi which came out to be extremely unexpected and weird. She reached her department (surgery) and the professors briefly introduced the field. A professor guided the students throughout the campus. He enquired about their accommodation and told them they have to stay at the hospital 24/7.

He went on to tell how hectic their lives are about to become and there will be days they won't be able to get any sleep or food. He advised the students to always carry their food and stay hydrated. 

He told them about the AST or the AIIMS Standard Time which is 15 minutes ahead of the entire world. He further directed the students to the Ward and introduced them to the Senior Resident. On reaching the ward, 3 seniors were assigned to the group to guide them further. The students were assigned work that continued till evening.

My friend's roommate asked him if he wanted to join him for a campus tour to which he eagerly agreed. The walk through the campus was never ending as there were so many things to see. They spotted a barber salon on the campus and a coffee spot. There was also a 24/7 library and a late-night ice cream tuckshop.

Overall first day at AIIMS is unpredictable with a lot of surprises that might leave you anxious. But the excitement of making it into the dream college overshadows all such anxieties!

Honestly speaking there is no distinction between those who cleared the AIIMS entrance exam on the 1st attempt or 3rd attempt. AIIMS Delhi just admits around 350 students over the period of 5 years leading to a family-like bond among all students. No one is outcasted or made to feel inferior just because of the number of attempts they took to clear the entrance. What matters is that eventually, you managed to get into AIIMS Delhi which in itself is a great feat. 

It's better you discard such negative thoughts and focus on your studies with positivity. 

Every student who is from a financially weak background with big dreams must have felt ethereal happiness on getting selected for AIIMS Delhi. The same was the case with my sister. 

Hailing from a middle-class family with limited funds to support her education, she was elated when she found out about her admission. She knew that getting into AIIMS was just the beginning and not the end of her dream, but getting into AIIMS Delhi in itself wasn’t a cakewalk. It brought her one step closer to her dreams. Today she has almost completed her degree and is on the verge of achieving her dream!

I’ll be sharing with you my opinion on both.

As a 6-year MCh candidate, you’ll rotate through 10 months of general surgery. However, general surgery skills aren’t of much use in Neurosurgery, except the very basic knot-tying and suturing skills. You can also acquire those from dedicated lab practice. The other techniques followed in Neurosurgery are very different from those followed in general surgery. 

Neurosurgeons generally use access surgeons (thoracic surgeons or urologists) to perform unconventional approaches to the spine. It is much safer for the patient. Also, opting for a 6-year course after MBBS means one less entrance exam.

So it isn’t very beneficial for you to take up 3 years of MS general surgery. I would recommend you choose the direct 6 year Mh Neurosurgery course at AIIMS or NIMHANS instead.
