We're looking for trends. Obviously, if your aggregate score is 75, you're passed.But, 0 I'm looking at what's going on in the vicinity of 50 because I don't think my point scheme is that accurate.

很明显我们在寻找发展动态，如果你的总分是75分，你就通过了，但是，我在寻找50分左右的同学的发展动态0,因为我不认为我的分值安排是正确的。

I have the freedom to pass that person because I like the trend. Suppose I have somebody else who came here with two years of chemistry in high school, got a 95 on the first test, 70 on the second test, failed the third test, failed the final, has an aggregate score of 48.

我能够选择让那人通过,因为我喜欢他的进步，假设另一个同学,学了2年的化学在高中,第一次测试得到95分，第二次70分，第三次没通过，期末考也没通过。
