To remedy your English skills in junior high school, you can follow these steps:

1. Review basic grammar: Focus on the parts of speech, verb tenses, and sentence structures. Practice by writing sentences or doing exercises online.

3. Read English materials: Read books, articles, and stories to improve your reading comprehension and expand your vocabulary. Highlight unfamiliar words and look them up.

4. Listen and speak: Immerse yourself in English-speaking environments, such as watching English movies, listening to podcasts, or joining language exchange groups. Practice speaking with a language partner or a tutor.

6. Take practice tests: Use past junior high English exams to assess your progress and identify areas needing improvement.

By consistently practicing these methods, you can gradually improve your English skills.
