I have few friends from IIEST Shibpur and I will try to give you a brief idea about the campus life based on what I heard from them.
Life is awesome at IIEST Shibpur. The campus is surrounded by greenery everywhere. The campus has lush green trees near the bank of the Hooghly river. The campus has two big grounds, one is named Oval and the other one is named Lords.
IIEST Shibpur campus gives priority to sports. Most of the students play cricket and football on campus. There are also facilities for table tennis, badminton, basketball.
There are a lot of clubs and societies on the campus, which you can join based on your own interest. I am mentioning a few club details here. Have a look.
The environment at the campus is great for academics. There is Ramanujan central library. The library has a great collection of books.
Coming to the annual fest, i.e. REBECA, it is a fun-fledged event. Hope this gives you some idea of what to expect from IIEST campus life.
