Since your still at your schools level I think it’s going to be a combination of great work + great presentation skills.
Some designers do great work, but don’t necessarily present it well. Making sure you have a really sharp presentation is going to count as much as the work you’ve put behind it. You want to figure out a way to keep the audience very engaged, without it becoming a list of your projects.
Of course having great work makes telling that story much easier.
Good luck.
