Watching Movies to Prep for Exams
If you’re preparing for TOEFL or IELTS, mastering idioms can substantially enhance your listening, reading, and speaking sections. While idioms aren’t overtly tested, they often appear in audio recordings or written passages. Moreover, using idioms naturally in speaking and writing tasks can demonstrate fluency, range of vocabulary, and a strong command of English.
One of the most enjoyable ways to learn these idioms is through movies—especially well-known films filled with everyday expressions.

Why Movie Idioms Matter for TOEFL & IELTS

-
Natural Usage: Examiners look for language that sounds natural—idioms help achieve that.
-
Exposure to Different Accents: Movies provide a mix of American, British, and other English varieties.
-
