20k in debt before Med School?

Can you share what they did to figure it out? We will be dealing with year 1: 3 in school, year 2: 3 in school, year 3: 2 in school, year 4: 2 or possibly 1 in school (depending on graduating early). I’m struggling with coming up with the worst case scenario for total amount / how much year 1 financial aid offer will decrease over the 4 years.
