LOS ANGELES (AP) — On a recent afternoon, Grant Oh zigzagged across the University of Southern California campus as if he was conquering an obstacle course, coming up against police blockade after police blockade on his way to his apartment while officers arrested demonstrators protesting the Israel-Hamas war.

In many ways, the chaotic moment was the culmination of a college life that started amid the coronavirus pandemic and has been marked by continual upheaval in what has become a constant battle for normalcy. Oh already missed his prom and his high school graduation as COVID-19 surged in 2020. He started college with online classes. Now the 20-year-old will add another missed milestone to his life: USC has canceled its main commencement ceremony that was expected to be attended by 65,000 people.

His only graduation ceremony was in middle school and there were no caps and gowns.
