I just graduated this past December. While most of my college buddies were spending their time sleeping or 'enjoying school', I was asking myself the same question you are right now. I concluded that if I wanted to be one step ahead of other college students, I had to be somehow proficient in a popular programming language. To execute that I did two things during my free time: I chose to develop small projects in python and django. And, also looked for internships to gain some real life experience because I knew college wouldn't prepare me very well. Thinking that way opened several doors for me after school (I graduated with several job offers). Also, college time is a crucial period of your life that will structure and define most of your thinking process. So make sure you spend time working on that as well. What do I mean by that? Make sure you are spending time working on your becoming a better version of yourself not only career wise but also personal. Spend time exploring yourself finding out what you like and what you want as a person. I hope it helps, you are in a great path already.
