備註：
(1) 熱騰騰的考題，雖然老師似乎沒有說什麼限制（但是題目卷有收回），可是只有前人
遺愛，才有後人乘涼，故整理了一下po上來

(2) 題目是小精靈生出來的，不要問、很可怕，配分和題目內容我保證有 99.99% 相同。
然後今年很...的出了50%名詞解釋，真的有夠xx，而且助教說會考的專題部分，通通變
成方法、步驟、結果，同學的愛心都白廢了，整體上考試體驗非常糟，希望未來不會再
這樣了QQ

(3) 考前有組讀書會+共筆，雖然不能說猜題準，但還是有不小幫助，至少有看過的話，
不會完全空白不知道要寫什麼，專題的部分就有啥寫啥，反正改題同學有說，只要有把
關鍵字寫出來，基本都給過~

(4) 考完老師會站在外面賭人，希望給建議跟改進的部分，同學千萬別客氣，有什麼抱怨
盡量說，這樣期末應該會比較好過一些，不過會調分，所以考爛應該也不用太擔心XD

Steven我一直看到你在共筆上顯示為在線，都懷疑你考試時坐我旁邊了，來認親一下XD

客氣了啦，共筆是大家一起努力的成果，我也只是順水推舟而已，有機會來認識一下:)

沒錯，一個致敬的概念XD；我們這次的專題同學，都有事先公布要考的內容，題目還有解
答，本來以為只要背好他們給的就行了，結果老師都改成別的了QQ

真的，感覺沒什麼意義QQ
希望是XD，因為幾乎所有的方法都是ML…- -|||，希望給分鬆一點QQ

補一下，結果滿分106，100以上都算100分，平均88，改題有夠鬆，基本上應該是有寫有
分了吧XD，不確定期末成績會怎麼說(雖然還是有人考4x…QQ，是不是沒看我們的共筆啊
