send in .. to send in one's name . . Theexamina

send in подавать (заявление); представлять (работу на конкурс, картину навыставку и т.п.) to send in one's name записываться (на конкурс и т. п.) Theexamination is very difficult; I don't send students in until they're fullyprepared. All reports must be sent in by the end of the week.
