@ehcsrc, for highly accomplished applicants like you who are aiming for top CS schools, UIUC, UMD and Purdue are a common trio of schools to apply to that are somewhat easier to get into vs your high reaches. You have an advantage at the first, being an IL resident.
Then, possibly followed by UWisconsin, UMass Amherst and maybe Virginia Tech or some such school.
You definitely should trim down your list of high reaches. It’s very hard to customize your application for all of them.
