from abroad -Full-tuition scholarships--for my son- for computer science

I think you get to choose: Is full tuition (or full ride) most important or is someone else’s made up list of top schools most important.

There “top” schools don’t often guarantee that kind of scholarship - because they don’t have to.

On the other hand, a full tuition scholarship might be available from a quite good school. But they almost always look at both English and math plus grades.
