A: This week has been crazy so far.
I've had two tests and a quiz.
And it's only Wednesday!
^^^^^^^^^^^^^^^^^^^^^^^^^^^
這是指所有考試均排在禮拜三嗎?!
B: I know.
It's gets really busy toward the end of the quarter.
^^^^^^^^^^^^^^^^^^^^^^
請問這裡指的是"約倒數1/4學期"嗎?

還只到禮拜三（還有禮拜四、五），就已經考那麼多試了quarter一般是指3個月(1/4年)，美國學校通常分成Spring/Summer/Autumn/Winter quarter，所以差不多就是指這個學期quarter快結束的意思。
