As a language learner, it's important to identify the root cause of your difficulties with English. Is it vocabulary, grammar, listening comprehension, or speaking skills? Once you pinpoint the problem, you can take targeted steps to improve.
For vocabulary, create flashcards and use them regularly. Read English books or articles that interest you to encounter new words in context.
For listening comprehension, listen to English audio books, podcasts, or watch English movies with subtitles. This will help you understand the rhythm and pronunciation of the language.
Improving speaking skills requires practice. Find an English-speaking partner or join an English club where you can speak and be corrected. Record yourself speaking and listen back to identify areas for improvement.
