I am presented with a list of school specific forms (some schools in which I have not even applied to). How do I know which ones I need to complete, and by which date?
You only need to fill out the school specific forms for which you applied. Schools are only listed on IDOC, if you listed them on your CSS profile originally. If you later changed your mind about applying to these schools, they remain in your CSS profile, but you don’t need to fill those forms out. Deadlines for Financial Aid, are listed on each school’s website and aren’t tied to IDOC, but normally are ASAP, in regards to Merit and Financial Aid. If college portals, say you’re missing forms, get on them, one by one.
