Switzerland follows ICAO Annex 2 / SERA.3415 exactly — no deviations. The VV answer key has 9 out of 11 light signal answers wrong.

The app answers follow ICAO/SERA.3415 correctly. The VV answer key appears to have systematic errors in the light signals section — answer letters seem shifted. The letter mismatches are NOT due to option shuffling; the VV key genuinely points to wrong options.
