It seems the list is solely based on parental perception of prestige. I hope the OP rethinks their application plan after reading this thread and showing to the parents… it does not seem that either fit or affordability have been researched as yet.
OP, do not be discouraged. There are excellent schools that will be a fit for your profile and help you achieve your career goals. You’ve got this! Keep asking questions and please be open to the responses.
ETA: As others have stated, looking only at T20s is not the same as top schools for CS. You need to look for schools strong in your major AND that fit your academic profile for the best chance at acceptance and most importantly having a happy and successful four years.
