1. Build a solid foundation: Master the alphabet, phonetics, and basic grammar rules. Practice daily to improve your pronunciation and listening skills.

3. Immerse yourself in English: Watch English movies, listen to English songs, and read English books or articles to familiarize yourself with the language in different contexts.

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

6. Stay motivated: Set achievable goals and celebrate your progress. Remember that learning a new language takes time and perseverance, but with consistent effort, you will see improvements.
