To improve your English proficiency in junior high school, you can follow these steps:

1. Build a strong foundation: Focus on mastering basic grammar rules, vocabulary, and pronunciation. Use textbooks, online resources, or apps to practice regularly.

3. Practice speaking: Find language exchange partners or join an English club to practice speaking English with native speakers or other learners. Don't be afraid to make mistakes; they are part of the learning process.

4. Keep a diary in English: Writing daily can help you remember new words and phrases and improve your writing skills.

6. Set goals and track progress: Create a study plan with specific goals, such as learning 10 new words each day or completing one grammar exercise per week. Monitor your progress and adjust your plan as needed.
