You should only get those items that are essential and basic that you might require in the beginning. During Diwali, you will get a 10-day break after 3 to 4 months of classes beginning so you can think of getting more luggage than if required.
The campus is quite close to the main city and you can get all other basic necessities like mattresses, stationery, and other things easily. You can also shop online if you like.
But, mainly, you need to have a good smartphone and a laptop. If you don’t have a laptop at home, you should buy one before coming to college. If you don’t have that you can also buy a laptop here once you know which one you need. Buy it before Diwali though.
Lastly, you can also get some medicines that you need on a daily basis. This was all that most students bring on a regular basis.
