To improve your IELTS Listening skills in one month:

Create a structured plan focusing on different areas each week.

In the first week, focus on getting familiar with the IELTS exam pattern and understanding the structure of each section.

In the second week, focus on practice tests and identifying weaknesses.

In the third week, practice listening to different accents and increase your exposure to English by watching shows, listening to podcasts, and using apps.

In the final week, focus on full-length practice tests under timed conditions to simulate the actual exam.
