Why this happens to Vietnamese speakers

Translation from another language produces combinations that are logical but not natural in English, for example 'do a mistake' or 'big traffic'. Examiners hear these immediately.

Why this affects Vietnamese speakers: Vietnamese does not mark tense or plural on the word itself, so these endings are easy to omit in English.

Vocabulary range can be narrow, with repeated common words.

A strength to build on: Strong learning motivation and regular study habits support steady progress.
