人生沒有用不到的經歷

高三常有考試，下面是常見的情況：
I had a math exam today. It’s horribly hard. (今天我們考數學，可怕的難)
I worry about failing the exam. (我擔心會不及格)
Teacher Sun said some of us were doing very well. (孫老師說有些同學考得不錯)
I don’t know how they did so well. (我不知他們怎麼考那麼好)
My trouble comes with geometry. (我的問題出在幾何學)
I am weak in relative positions of figures. (我對形狀的相對位置感受很弱)
I passed two tests on algebra with high scores. (我通過兩次代數考試，分數都很高)
But when it comes to geometry, I got scores below 70 twice so far. (一提到幾何，迄今有兩次低於七十分)
It’s like I am studying and studying and I feel prepared. But I got bad grades though. (似乎我一直讀一直讀，感覺準備好了，但分數還是很差)
I am wondering if I would still be able to succeed in application for medical school. (我開始懷疑我是否還能成功申請進入醫學系)
The grade of math below 14 in General Scholastic Ability Test (GSAT) is not acceptable. (申請進入醫學系，數學學測低於14級分是無法被接受的)
To head toward math GSAT grade above 14, I think it’s time to change my study strategy for geometry. (邁向學測數學14級分，我想現在正是時候我要改變幾何的學習策略)

前兩句也可以是：
I had a math exam today. It’s pretty easy.
I study it inside out. (我懂得很透徹)
I practiced all questions twice in textbook and took extra courses after school. (我演練教科書上所有的習題兩次，放學後，我到補習班上課)
I did twice as many exercise questions for the exam. (我做了兩倍的練習題準備這次考試)
