Here are some of the things that you should keep with yourself on your first day. 

• You're going to become an engineer soon, so keep a ballpoint pen with you. 
• Try to keep a piece of paper too for nothing down important points. 
• Keep copies of your documents with you. 
• The first day is communication day, so you have to introduce and give a summary about yourself. 
• Remember the number you registered for, and above all carry some money as tea break snacks are available in the Morning. 

So, to put it straight, bring a notebook with a pen if you are a day-scholar. If you are a hosteler, consider the things relevant to your accommodation. However, at the Sarvodaya Sangh outlet inside Institute premises, all the basic Hostel accommodation needs including bed, pillow, bucket, mug, lock, etc. were available.
