I finished the lesson with BEFORE and AFTER, but I find it difficult to say the sentence backwards. For example, if I want to say: I studied Japanese before I went to class., I have to say in Japanese: じゅぎょうに行く前に日本語をべんきょうしたの。 so it's backwards. I mean, first you have to say that you went to class and then that you studied Japanese. But in English/Romanian (my native language) is the other way around.
Is it a way to say things in the same order as in English/Romanian this things? Because with 時に it's easier.
I hope you understand what I said. >.<
