financial aid isnt enough

okay so im so grateful that i got into DKU itself but the thing is that i got a low scholarship and i doubt i could afford attending (my cost of attendance wld be ~$50k). i have appealed for a higher scholarship but could any current students lmk if theyve been in a similar situation and their appeal got accepted. i can afford like $20k and thats pushing it so thats a big jump from 50k. how unrealistic is a 30k increment on the scholarship. also just incase if my appeal gets rejected is it feasible getting a loan to get into DKU as an international student?
