Attach yourself to the hip with the peoples’ movements. That can mean anything from immigrants rights, tenant and workers unions, community defense, mutual aid societies to student organizing and LGBTQ+ advocacy.
The point is to use your knowledge of Marxism to advance the struggle to levels impossible under liberalism, and then you win over people to Marxism through your practice.
You’re never going to win over people to Marxism by mere persuasion alone. You need to show them in real-life the scientific nature of Marxism.
Edit: For your specific case, you need to focus your efforts on a campaign. Use your knowledge of the local area to see what issue students care the most about and then organize around that issue. If people care about said issue and your outreach is good, people from the community will come forward and join you.
Edit2: When choosing an issue, the more existential it is to a particular constituency, the better. That’s how you get hard-working activists.

This must have been how people felt like when the Tet Offensive destroyed the government narrative surrounding the Vietnam War, the narrative that the Vietnamese were eminently about to capitulate.
