The test papers from Xiao Xiurong and Jiang Zhongting have been market-certified for many years, and have a high probability of hitting the mark.
That's why they have such a high market share.
As for New Oriental's English, it goes without saying, their reputation has been very stable over the years.
However, succeeding in the postgraduate entrance exam is still only in its first year.
Moreover, as the final month of exam preparation approaches, everyone's mindset is no longer as stable as before.
They begin to grow more restless and anxious.
