It is good that you want to learn and explore your field in first year itself. You need to first learn things and then you can simultaneously complete few projects that will give you practical experience and will be helpful in future.

You can do some courses like

• Graphics Designing

Focus mainly on improving your computer language skills

See,if you want to explore your field there is so much to explore but you need to first make your basic background so clear that it will help you in understanding advance level courses very easily.

You can take courses on Coursera,EDX,Udemy, NPTEL and even on YouTube. So many free resources are available too so make use of the.

First ask your professors that what you should learn and where,they will help you and it will also make a good impression.
