Why does UCSB suggest quarterly payments for housing/food?

I’m filling out my housing for UCSB right now and I saw that it suggests quarterly payments for those who are receiving financial aid? I’m king of confused, because monthly payments seem easier to me since you pay less at one time? The only financial aid i received was the freshman scholarship and possible work study. Essentially im wondering which is better, quarterly payments or monthly payments??

Because those who receive financial aid receive it quarterly
