Start Thinking In English
You could begin your journey of mastery in IELTS and possibly mastery in English by beginning to think in English.
e.g. when you wake up in the morning and it is raining heavily, you will think to yourself, in English, “Oh! It’s raining heavily today” and not in any other language.
I would like that you eventually reach a level that when something happens instantly the knee-jerk words that you think/utter are in English.
