Hi Patrick,
Since your paper doesn't require any sources, you should write your essay from your own experience and perspective. As you are writing your essay, you can reflect on your college experience as a first-year student and then frame your paragraphs around that. You should ask yourself questions, such as, What advice do you recommend for incoming first-year college students?, What do you advise new college students should do during their first year?, What information you wish you would have known?, and Is there anything you would not recommend to incoming college students?
Since you are finishing up your first year at college, you have a whole year of experience to reflect and tell others about advice, tips, and suggestions for incoming college students. You should frame your paragraphs with ideally one topic per paragraph to make the essay flow more easily.
Hope this works. Good luck!
Krista
