回復 @lizhenxuan：That's not your fault. The high school life is tiresome and cruel, especially for the last year. Limited time should be lived in a relaxing way.

回復 @lizhenxuan：Welp... how many words you don't know in one passage in the exam?

By the way, as for English courses in a university, there are four courses in two years (one in a semester). But usually students learn English by themselves.

回復 @啊啊是誰都對：The number of unknown words in a passage is up to its difficulty.  In a relatively simple one, it may be 1~3 words I don't know,  while this number can be uncountable in a difficult one. 

回復 @啊啊是誰都對：However,  a difficult passenge often means easy questions. I mean the correct options are often easy to find. 

回復 @lizhenxuan：Welp, your situation is quite similar to mine in high school... then I suggest you to fix yourself on the exam. Your vocabulary is enough for this exam.

Then only to recite these words you don't know in these passages. And give more time to other parts.

回復 @啊啊是誰都對：Alright.
