How I Got a 7.5 Band Score In My IELTS Exam On My First Try Even Though I am Terrible With English and Had Only 2 Weeks to Prepare..
 
The high-score formula works effectively because of 2 reasons

(1) It is a straightforward and easy formula that doesn't require a lot of time for you to prepare for the exam (HINT: Many people fail the IELTS exam due to all the stressful and time consuming methods around)

(2) It helps you to focus on the main areas that get you high results in each section of the IELTS exam (Listening, Reading, Writing, Speaking)
This high-score system also makes it easy to answer any question you are asked regardless of whether you know the answer or not.
With this formula, you don't have to spend hours upon hours at study centers like a lot of people do to prepare for their exam.
