No GPA for my major, either (Landscape Architecture).
I asked the lady in the career service, and she said no Art Major is necessary to put their GPA in their resume. Good for us, eh?
I guess our resume is quite different, though. We put our work sample pictures and all nicely designed, with our names, logos, etc. We use Adobe InDesign/Photoshop Program instead of Microsoft Word. So much colors and varieties in our resumes than business or med resume.
Anyhoo, good luck for all who start to find a job (including myself).
