What a 6.5 sounds like
Do you remember a long walk in your childhood? — Yes, I remember that when I was a child my family often went walking in the mountains near our city. We walked for many hours and it was very tiring, but the air was fresh and the views were beautiful. I have good memories of those days.
How often do you walk now? — Not very often, unfortunately. I usually take the bus or the metro because I am busy with my studies. Maybe I walk twenty minutes a day, mostly to the university and back.
Where do the people of your country like to go for walking? — In my country people like to go to parks and to the mountains at the weekend. Parks are popular because they are free and there is fresh air, and families can take their children there.
Why it scores what it scores: Accurate across all three tenses, which is what the set is testing, and the middle answer does the right thing by giving a number. The first answer is where it loses ground: the question asks for one walk and gets a summary of many, so no narrative language appears at all. Nothing in the answer could only have happened to this candidate — fresh air and beautiful views would fit any mountain anywhere.
