Everything that Jess said is true!
Also ... definitely write a Summary or Qualifications at the top so that reviewers will know what you're aiming for/what you bring to the table.
For example ... say you want to be an office manager for a nonprofit (this is a totally random example). Maybe you'll write that your excellent organizational skills allowed you to maintain an excellent GPA. Or that your interpersonal skills allowed you to succeed in collaborating with others in ______ circumstances. Look at the job posting and address their desired qualifications this way. I usually do mine in bullet form.
