GPA. As mentioned above, your GPA is only necessary if you are a recent college graduate and do not have work experience to back you up. There are a few jobs that require a GPA, however, including engineering and finance.
There are some things that don’t belong on a resume for a job. What you exclude is just as important as what you include. Ideally, your resume should reflect experience that is relevant to the job you are applying to, and typically no more than ten to fifteen years in the past. Since your resume should, if possible, be no longer than one or two pages, you may need to nix certain items.
