A student resume for an internship or entry-level role should highlight relevant coursework, campus involvement, projects, and any part-time or volunteer experience.
List courses directly relevant to the role you want, and describe class or personal projects the same way you'd describe a job: what you built, what tools you used, and what you learned.
Retail, food service, tutoring, or campus jobs demonstrate reliability, communication, and time management -- all transferable skills worth including.
