There is no extra timing for English every day. Apart from English lesson (20mins for K2), the class has different grouping time, Some groupings in Chinese, some in English.
If you just look at the time-table, the time-table for each class is sticked on the board.
You can see it during the orientation day. (first school day)
The English Lesson for each day is 20 mins as stated.
Each day, there are 3 different grouping time and 1 topic time (also 20 mins for each). Some are also lead by the English teacher.
For example - English reading (reading of the Oxford Reading Tree), each student has to read it out to the English Teacher on their own. This is also arranged during the grouping time.
