Definitely! I highly encourage you to be active in your college even if you are a full-time student. Student organizations help you to meet new people, they look great on your resume, and they're fun! Also, when it comes time for you to interview for jobs, recruiters/interviewers love to hear about your experiences in those student organizations. It's always great to have leadership experiences because they could help you answer a question asked by your interviewer. Eventually, you may chose to be an officer for your student organization and that will also look great on your resume!
There's a ton of student organizations in college. Consider joining a student organization that's relevant to your interests or major. Most importantly, use the opportunity to learn something about yourself, serve the community around you, grow as a person, meet new people and have fun!
Thanks for reaching out for advice! Good luck, Nathali.
