I will be a great class president because I care about my classmates. To be successful, we all must be successful together. I will make sure that we all improve our grades, have time to enjoy our extracurricular activities, and have time to make school a better place together. I will ensure that homework is reduced and our classes are filled with everything we need to be successful. I will make sure that people who need help with subjects have tutors and extra time to study. Thank you.
