Vietnam’s high school graduation English exam is designed to challenge students aiming for top marks. According to educators, questions focusing on reading comprehension summaries, inference, and difficult fill-in-the-blank or idiom exercises are specifically intended to prevent a high number of perfect scores. These question types act as obstacles for students seeking scores of 9 or 10. Success requires not only strong English proficiency but also a calm demeanor and strategic approach to answering. The exam aims to differentiate between students with a solid understanding and those with superficial knowledge. Students are advised to prepare for these challenging formats to maximize their potential scores. These question types test a deeper understanding of the language beyond basic vocabulary and grammar.
