I was originally in a program called Digital Media, and then switched out two years later into Business. I wanted to add Digital Media to my resume since I did learn some relevant things in that program. How do I list that?
If you studied "Digital Media" for two years, without obtaining any formal qualifications, I am sure you will have acquired a broad range of digital media skills.
You should not list those skills under "Qualifications" (unless you obtained some "Diploma(s)" for particular competences), but you could certainly list them under "Interests"; "Hobbies"; or "Experience":
Other Relevant Interests and Experience: ―――――――――――――――――― Digital Media, including digital photography and post production editing using .......
However, in my opinion it is only worth listing such things if they really ARE somehow relevant to the job (or course) you are applying for.
Often people will list the number of hours earned toward a degree on resumes and note if they are still pursuing that degree in the education section. I agree with Santa that you should only list it if you feel it makes you more qualified for a particular job. Some may view an unfinished degree as a negative thing. FWIW I have a Bachelor's degree in computer science and 18 hours of grad school. I used to list the post-grad work but now that I have over 20 years of IS/IT experience I figure that it is a waste of space on my resume and just list my completed degree.
This ^^ is absolutely spot on in my opinion.
