Shir Lal Bahadur Shastri Government College is one of the best government medical colleges in Himachal Pradesh. Populrly known as NER Medical Chowk College. Since it offers only one stream, which I can currently see, is MBBS in Medicine and Health Sciences. However, if you have not yet decided to take admission in this college, I can only advice you to look at more popular and well known colleges because there are no detailed information about its placements, or peer reviews available on the internet which is generally not a good sign since you plant to move from 0.2m altitude to hills of Himachal Pradesh.

As far as facing difficulty due to hill stations, it is nothing unbearable. Season changes in North are more prominent. You can actually feel the season changing from the air chillness. However, the scenic beauty is something to look forward to. Mandi is one of the known hill stations that mainly people visit and is also located quite near to other well known hill stations such as Shimla.

If you need more information please feel free to comment.

I wish you best of luck.
