Graduation = the receiving or conferring of an academic degree or diploma (most often during a ceremony)
Graduate = a person who has successfully completed a course of study or training, particularly an undergraduate degree
(undergraduate) degree = university certificate or bachelor's degree
Interrupted = interrompido por um tempo ou para sempre
Suspended = interrompido por um tempo
Discontinued = interrompido para sempre
And it's the studies that are interrupted, suspended or discontinued, not the degree or the graduation.
Minha sugestão: Undergraduate studies in Computer science interrupted/suspended/discontinued for personal reasons
