I created a table to transform the average points to a 30 points scale. I updated the following post with them:
How do they grade the Speaking section?* The Speaking section contains six questions, and each one is scored from 0 to 4 points without decimal values.
For example, you can obtain the following set of results [4,4,3,3,3,3]. Then, they calculate the average of the results (sum of the the six scores divided by number of elements):(4+4+3+3+3+3) / 6 = 20 / 6 = 3.33 and the outcome (3.33) is converted to a 30 points scale.

That means that you can score 4.5 or a 4.0 in one of the questions, but you can't get a 4.25.
For example, lets say you obtain the following set of results: [4.5,4]. Then, they calculate the average (sum of the the two scores divided by number of elements): (4.5 + 4) /2 = 9.5 / 2 = 4.25 and the outcome (4.25) is converted to a 30 points scale.
