There are there's a lot more important stuff you could be studying and I have seen students write long lists of vocabulary, long lists of idioms.

还有很多更重要的东西你可以去学，我看到过有学生写了一长串的词汇，一长串的习语。

This student will often also memorize lists of vocabulary, lists of idioms, lists of phrases, and this will actually lower their grammar and their vocabulary score because they'll never be able to use them effectively.

这个学生通常还会记住词汇表、成语列表、短语列表，这实际上会降低他们的语法和词汇分数， 因为他们永远无法有效地使用它们。
