@K_miso this post is what you need to look for in the fine print for your other colleges. Or maybe for this one.
At minimum, they were looking for you to cover travel and personal expenses. If you put 0 then you did not demonstrate the need they were looking for.
Budget all of that out and then if you see that again you will know if your plan is viable.
Have you budgeted what those costs would be?
How much are flights to the US snd back?
Where will you stay during breaks between semesters and how will you pay for that? Do you have extended family here? How would you pay for travel to see them. Even if a dorm is an option, dining halls may be closed, so you will need good during breaks.
How would you pay for items needed for your dorm room? Where will you store those items in the summer? What will that cost? Many international students can not also work here depending on their visa, can you save money money from jobs at home? Tally all of that up so you know all of your costs?
