TESC Computer Science

[Yenisei]

Since this program is taught in English, I don't know why this is in German, but here is what they say will work for entry into the program:

Raumfahrttechnik, Elektrotechnik, Mathematik, Physik, Informatik, Geodäsie, Geophysik

Aerospace engineering, electrical engineering, math, physics, computer science, geodesy and geophysics.

EDIT: after having had a look at the course structure, I suspect that your son will only need Calc I-III, Diff Eq, Partial Diff Eq and maybe Linear Algebra as far as math goes, and some calculus-based physics would also be useful. Since it's possible to use CS courses in the NS degree at TESC, maybe that's what the professors will advise him to do.
