According to Prep Scholar (take it for what it’s worth - they had the averages of all schools on one site and I was too lazy to calculate averages from ranges on each schools’ web site)
RIT average SAT 1290
Case Western average SAT 1440
DePaul average SAT 1190
UDel average SAT 1290
Arizona State average SAT 1210
GMU average SAT 1210
1270 is below the average for half of these schools. I think ASU is a great option, I wouldn’t waste the application fee on Case Western. If GMU and DePaul are within your budget then apply, I’d worry that my kid might be “weeded out” at RIT and UDel with that score and GPA but you know your kid, some are great students but not great test takers so maybe they’ll shine like @thumper1 's DD. Good comp sci programs for an A/B student with a 1270 would be ASU, UT San Antonio not Case Western and the like. It’s important to find a good fit, the good thing about comp sci is it’s more important what you DO than WHERE you go when it comes to finding a job.
