Receive good grades in your classes. Do your homework on time and always study for tests at least a week ahead of time. If spending time with your friends sounds better than studying for a test, think about how it may affect your chances of getting accepted into the college of your choice. Also take advanced courses in high school to show college admission officers that you challenge yourself.
Participate in extracurricular activities. Show college admission officers that you make good use of your time after school. Join sports teams and clubs at school. Also do volunteer work or community service. For example, you can volunteer at your local hospital or homeless shelter during the weekend.
Excel in sports if you are athletic. Whether you play football or basketball, work hard to get noticed by college scouts at the games. Always attend practices after school and get plenty of exercise to keep yourself in top physical shape. Maintain good grades to show college scouts that you can balance school work and sports.
Write a college essay that will impress college admissions officers. Don't simply list your extracurricular activities and the academic clubs you participate in. Let the admissions officers know how you are different from the rest of the applicants. For example, if you are an artist, write about what got you interested in drawing or painting. Also explain in your essay why you would be a good fit for the college.
