According to the efficiency theory, Xueba is completely weak relative to the school slag! Although the school is over 90 points, 60 points are taken.
But Xueba used 17 weeks, 119 days! It took only 1 week and 7 days to learn the slag! Therefore, the slag used only 5.8% of the time, and completed the 66.7% workload of Xueba.
Therefore, the learning efficiency of Xuexue is 1133% times that of Xueba!
