I need my greades from all classes taken
I believe that you may be asking for your transcript, which lists all your classed attempted and finished on the ASU Newport campus. This request is handled in the admissions office. They have a link to request your transcript on the ASUN.edu main webpage.
If you need any assistance, you may contact them by phone at 870-512-7725 or toll free at 1-800-976-1676.
