It's a digital world - Look at how you consume and participate in media - blogs, FB, twitter, etc. Are there any aspects of them that you enjoy, contribute to? Have you started your own meet-up, blog. etc.? Document that, show initiative and creativity.
Marketing is about communication, solving problems, creating - what speaks to you?
As others have mentioned, marketing has grown to encompass a lot of different things. My advice to you would be to gain internships in various industries and departments! For me, this was the best thing I did for my career as I was able to learn things I did/did not like as well as learn different work styles and gain valuable mentors who have been key in my growth.
Make sure to have business cards handy when you network, and beef up your LinkedIn in case people want to explore your profile.

Another resource is doing HubSpot Academy certifications in your free time. These are free: https://academy.hubspot.com/certification-overview
Google offers free certifications for marketing. Here is the link: https://learndigital.withgoogle.com/digitalgarage/course/digital-marketing
Google also offers free webinars on marketing that can be fun if you have some free time and want to feel productive: https://learndigital.withgoogle.com/digitalgarage/f2f
HubSpot and Google certifications obviously aren't necessary, but they are something that you can do to gain more insight into marketing outside of what is being taught in your classes and are something you can put on your resume/linkedin early on if you don't have a lot of other things to add yet.

I highly suggest checking out the Google Online Marketing Challenge for students. It's a great way to learn how to run digital campaigns using Google search ads. First, you need a professor to be your sponsor. Then, you need at least one student partner. The two of you complete a Google Academy course on Google search ads and analytics. After completing the courses, your team gets paired with a real nonprofit that needs help with marketing. Google provides in kind money for a campaign, and your team works with your new nonprofit client to run a Google search ad campaign. At the end of it, you get a certification of completion. You also get to present your findings to Google, and you may be chosen for other cool opportunities like chatting with Google marketing staff, touring the place, or some people have even been hired to work there (very rare).
Either way, it's a really unique line for your resume, and it combines information you may learn in the classroom with real world application.
Besides this Online Marketing Challenge, Google has a whole skillshop where you can get certified in every one of their digital marketing products on your own time. It take dedication, but it really helps you stand out from the rest of the people graduating and those already in the field seeking jobs who don't have those certifications. Facebook and Instagram also have similar certification programs as well that could be useful.
If you are more interested in content creation, then something like Medium.com or simply utilizing the article writing feature on LinkedIn could be really helpful. You can create longer SEO rich pieces targeted towards the industry you would like to work in, and by doing so, build a portfolio that employers will be able to see when they look at your LinkedIn, or just drop a link to your Medium page on your resume.
Lastly, the United Nations has a spot where nonprofits from around the world post want ads for volunteers to help with things like creating marketing strategies, launching campaigns, redesigning websites and creative, etc. It's all volunteer based, so these aren't paid. You can check out the ads and then apply to one to see if they would like you're help. These are kind of hard to do and might be for more established people in the field, but it's worth it to check it out. That way, you can see what kinds of services nonprofits and for profits might need in the marketing sector.
