Make several photocopies of all the forms you receive. Use the copies as working drafts as you develop your application packet. It's always best to type the application. If you must print, do so neatly and legibly. Proofread the entire application carefully.
Nothing is less impressive than an application with misspelled words or grammar errors.
Ask a friend, teacher or parent to proofread it as well. Compile a list of all your accomplishments. This will help you identify your strengths and prepare a better application. Give a copy of the resume to the people who are writing letters of recommendation for you. They will be able to work some of the tidbits into their letters, making it seem like they know you better.
