Suspension in highschool

Hi, I got suspended because I was involved in a stupid incident but since then I’ve approved and I’ve been trying to stay on the right track. My question is if you got suspended and the deans/counselors in the school say that it goes off my record if I don’t cause trouble for the rest of high school, can I trust that? Like if the college asks if I’ve ever gotten suspended and I put no, what could possibly happen? I’ve already asked the counselors in my school and they said that I could just put no and I would be fine but I’m honestly scared.
