To achieve a score of 125 on your English test in junior high school, you can follow these steps:

1. **Review the syllabus**: Understand what topics and skills will be tested. Focus on key areas such as grammar, vocabulary, reading comprehension, and writing.

3. **Expand your vocabulary**: Learn new words daily and use flashcards or word games to reinforce memory. Incorporate these words into everyday conversations to improve retention.

4. **Read extensively**: Read English books, articles, and stories to improve reading speed and comprehension. Highlight unfamiliar words and phrases for later review.

6. **Listen and speak**: Immerse yourself in English-speaking environments, such as language exchanges or English-only clubs. Listen actively and practice speaking to build confidence and fluency.

7. **Take practice tests**: Solve previous year's question papers or sample tests to familiarize yourself with the test format and timing. Identify weak areas and work on them specifically.

8. **Manage time efficiently**: During the actual test, allocate enough time for each section. Prioritize questions based on difficulty and quickly eliminate those you are least sure about.
