No, you certainly made the right choice by choosing LGMC over any other peripheral AIIMS. I have seen many medical aspirants run after the AIIMS tag and choose a peripheral AIIMS only to regret it later. Only the ones that have been established for about 5–6 years are worth taking admission in.
In my opinion, it’s better to go for a medical college that has a legacy of more than 10 years as it will be better academically, environmentally, and even in terms of the campus life it offers. Choosing LHMC will expose you to better opportunities especially because of its prime location in CP. Moreover, it also has Delhi Quota for MD. The clinical exposure is also unmatched and the internship opportunities will be plentiful.
So, put your worries to rest as you have made a wise decision by choosing LHMC over a peripheral AIIMS.
