Yes, AIIMS Delhi is definitely worth it considering the fact that it is one of the most prestigious medical colleges in India, and thus an MBBS degree from there is highly respected. What makes it worth it is the excellent faculty, state-of-the-art facilities, and strong research programs. However, the actual worth of an institution depends on the individual's goals and preferences.
It’s difficult to comment on whether joining AIIMS Delhi would bring joy to you in comparison to other state medical colleges because not many students have experienced both college lives and those who have experienced loved the overall program rather than the institute. In reality, the colleges don’t differ much and these little differences don’t affect your learning experience to a great extent. Everyone considers their college to be the best or worst when in reality every institute has its own strengths and weaknesses.
Every college you go to will be the best and offer a great learning experience. So don’t worry too much about your college and focus on what is being taught.
Many AIIMS Delhi students have reported that the academic rigor and resources at AIIMS Delhi are top-notch and that the campus community is very supportive. Some students may find the high competition and pressure to be stressful, but others may thrive in that environment. It ultimately depends on an individual's personal preferences and learning style.
