To improve your English score from 40 to a level that allows you to enter high school, you need to focus on several key areas:

1. Vocabulary: Start by expanding your vocabulary. Use flashcards or an app like Anki to practice new words daily. Aim for at least 10-20 new words per day.

3. Reading Comprehension: Read English articles, books, or stories to improve your reading speed and comprehension. Try to read at least 15-30 minutes every day.

4. Listening: Listen to English audio books, podcasts, or watch English movies with subtitles to improve your listening skills.

6. Writing: Write essays, diary entries, or short stories in English to improve your writing skills. If possible, get feedback from a teacher or native English speaker to identify areas for improvement.

By focusing on these areas and practicing consistently, you can gradually improve your English skills and achieve the required level for high school admission. Remember, perseverance and consistent effort are key to success.
