I’m preparing for my upcoming IELTS exam. How can I improve my speaking and writing? I must get 7.5+.

Yes, it is definitely possible to achieve a high IELTS score with limited preparation. Let me share my experience: I registered for the IELTS Academic test on December 22, 2020, and took the test on December 29, 2020. Despite only having a week to prepare, I achieved an overall band score of 8 (Listening-9, Reading-9, Writing-6.5, Speaking-8).
