I know posters require one of those big posters but can list a "presentation" if they presented their research during class or at a club meeting or something?
Poster and oral presentations imply presentations at a research conference where approval for presentation depends on the quality and novelty of your research. Presentation opportunities are often competitive.
Seems like you are just confused/playing around with words. A poster "presentation" or oral/podium "presentation" is just that--a presentation of your work. Plenary/keynote presentations are the competitive ones.
