Dear

Apart from your studies you should have good Numbers of Internship in respective domain.

Internship will give you professional knowledge and experience too.

You can watch Khan academy and code academy for more knowledge about coding and software related topics .

All the Best

Learning engineering is itself not satisfactory .. so you need to pull yourself and dedicate about 3 hrs daily studies for ur academics and research online for new technologies and learn , grow and explore yourself . Do more and more internships so that u atleast get an idea about how does industry work and how to react to professionals , how to talk to them and how to maintain an time management schedule . Doing online courses can vast your knowledge very well as you will learn and will know about many things till the end of 4th year and be a master in any field u choose.
