Hi,

Well as far as the listening part is concerned for IELTS exam then the following steps might ensure good score band in the actual exam.

1. Listen to podcasts over Spotify and other streaming websites for listening practice and try to make notes of the episodes.

2. Watch movies and shows with subtitles first and then without it. Try to listen clearly and understand each word they are using and also the overall gist of the conversation

3. Try to talk in English so that you will also get to hear back from your friends and relatives in English.

I hope this helps.

All the best.
