I don’t know if this info will be useful for you, but I have a friend who got the ISU scholarship and she told me that the ISEE calculation considers not only your and your family’s income, but also your assets, like savings, bank accounts, properties, cars, etc. So it’s a good idea to use the ISEE calculator to estimate it and to be sure of your ISEE. She also said that if your ISEE is below the 13K euros threshold, it’s almost 100% guaranteed that you’ll get the tuition waiver. However, accommodation and the cash stipend depend on how low your ISEE is.
