schnellstmöglich vs sofort
immediately
'sofort' and 'schnellstmöglich' both say that no unnecessary time should be lost. But 'sofort' means: right now, without waiting. 'schnellstmöglich' means: as quickly as possible in the situation. That may also be later, if something else has to be done first. Learners may confuse the words because both sound urgent. As a guide: if something should happen right now, 'sofort' fits. If something should happen as soon as possible, 'schnellstmöglich' fits.
