Ncsu has really become much harder to get into these last 6 years. It’s a really good school but being instate you really have the advantage. Look at the metrics for his school of what is needed to get in so at least you know how realistic it is.
If your willing to share his unweighted GPA and any stats and what math /science he will end in senior year that might be helpful. But of course you don’t have to.
If you look further though many other options at good schools like Iowa and Iowa State University.
Kettering and Michigan Tech.
Illinois Institute of technology.
I am sure others will list their favorites but all will get you good jobs. The last one will net you work locally at some of the largest firms worldwide…
