IELTS Reading and Writing - Question Number One

Samia: I was listening to your episode before I joined the course when I prepared for my third time IELTS. My score jumped from 6 to 7.5. And then I just believed in that course. So, let's start with question number one. What is the difference between two and half or what? We're discussing numbers that move and change. That's why we use two, because two describes direction,.
