Is tolce 18.7 good enough?

I entered my first eng tolc-e and got 18.7/36. I want to study business management or economics, preferably in uni of milan or uni of trieste as an international student. My gpa is already very mediocre, mostly because of my chronic ilness precenting me from attending much to school, and I will adress all of it whilst applying too. I know I can enter the exam again, but that'd mean I'll have to apply march 9th the earliest, and Im afraid of missing the deadlines for some of places I want to apply to/ getting rejected for applying late. I cannot afford an expensive school either, and I want to go to a somewhat known /recognizes school and not just any school. What should I do?
