English language ability is widely recognised as the essential attribute for success in the
Australian labour market. Under current arrangements, applicants must have a minimum score
of 6 in all four components of the International English Language Testing System (IELTS), for
which they are awarded 15 points. Applicants with a score of IELTS 7 or above are awarded 25
points.
这里是说4个6加15分,但是7分以上就加25分,而并没有说4个7?
不知道这个理解对么?还是这只是一个笔误而已?
