I'm 19 and doing my undergraduate studies in IIT Kharagpur. I am clueless as to where my life is heading. What are the various things I should learn during my 4 year stay here?

Honestly being in the first year at IIT is too early to be clueless. In the future, you will face hundreds of circumstances where you will feel clueless so don’t ruin your college life feeling clueless when you have so much to do.

• Don’t let your CGPA fall below 8 during the first year at IIT Kharagpur.
• Master programming languages such as Java, C, HTML, C++, Python, Ruby, or .net,
• Develop a startup mindset and start working on one early. By the end of 2nd year have your startup idea ready with a website.
• Master MATLAB/MATHEMATICA/COMSOL software. You need them for academics.
• If you are good at dramatics you can start your YouTube channel and start earning.
• Rather than depending on on-campus placements, get a PPO from the company you interned with.
• Maintain healthy bonds with your project professor.

I will suggest you not waste time looking for clues but rather make the most of your precious time at IIT. Explore your abilities and look for your passions and keep learning new things.
