@soxdad I think he will be fine for EA. They will see he is currently taking MVC/LA which is beyond what is available at his school and they will see his previous math grades. My son was in the middle of a research mentorship with NASA last year during the the application process. He was able to put it on his application, but unfortunately he was not able to claim being published as that didn’t happen until after college admissions were done. So unless his research will be truly published by the end Dec, I don’t think it will make much of a difference as long he has research involvement.
I am not going to tell you that he is going to get accepted to all or any of those schools as OOS for CS is so competitive but I just don’t see him getting knock out in the EA round with his stats as they are now.
