Resume for Recruitment

Thanks, I appreciate your advice but would that apply to resumes going to sorority alumnae who are writing recs and letters of support, too? I understand that much of the info would be the same but if someone was class president for 2 years, should they bullet the line and say "Class President-2 years?" Also, what if a person participated in the same event every year and had a different outcome, i.e. placing, or was in the same event multiple years, but in a different category every year?
