Past papers 3

“Past papers” means “past HKCEE/HKAL examination papers”. The topic is for Hong Kong students who are facing HKCEE or HKAL. But the general principles can also be used for tackling other public examinations.

千萬不要打算 “溫完書” 才做 pastpaper。因為書是溫不完的,你打算 “溫完書” 才做 pastpaper 的話,你將會沒有時間做 pastpaper。

我以前中五時有考會考(公開試)美術科。中三時的美術老師教了一樣考試技巧。會考時,會有三小時畫一幅畫。例如,那幅畫是一幅郊外風景圖。畫內有一間屋、一棵樹 和 一隻狗。假如,你畫那間屋時力臻完美,你就會花了大部分時間,導致沒有足夠時間畫那棵樹和那隻狗。整幅畫只有那間屋是完整的,你的美術科會不合格。

正確的方法是,第一步,先簡略描繪了屋、樹、狗的外型。然後,為 屋、樹、狗 加第一重的細節。還有時間的話,就加第二重的細節。還有時間的話,就加第三重的細節。如此類推。這個方法的好處是,無論考官在什麼時候宣佈 “停筆”,你也可以宣稱,你已經完成了那幅畫,不會不合格。

這可以引申做溫習和考試的什麼道理呢?

如果你打算 “溫完書” 才做 pastpaper,又或者 打算 “溫完” 一個 topic 才溫下一個 topic 的話,你很容易會不自覺地花了大部分時間於一個 topic,導致你沒有足夠時間溫其他 topic。例如,你對 mechanics 很熟,其他 topics 沒有足夠時間溫習,你整份 physics 卷的分數將會很低,甚至不合格:

    mechanics 18/20

    EM 05/20

    wave 05/20

    optics 05/20

    atomic physics 05/20

    total 38/100

但是,如果你不斷按年份做 pastpaper 的話,因為每年的 pastpaper 都有多個 topic 的題目,你每個 topic 即使不太熟,也不會太生疏。你整份 physics 即使不高分,也不會不合格:

    mechanics 12/20

    EM 12/20

    wave 12/20

    optics 12/20

    atomic physics 12/20

    total 60/100

在這個基礎,想再提升分數的話,可以用梅花間竹的方法,按年份做 pastpaper:

按年份做 pastpaper(要計時間和計分數)–> 溫習特定 topic –> 按年份做 pastpaper –> 溫習特定 topic –> …

溫習特定 topic 和按年份做 pastpaper 之間就有這個關係。兩者其實是相輔相成的。例如,你按年份做 pastpaper,發現次次也是因為某一個 topic 導致損失十幾分的話,你就可以知道那個 topic,正正就是你特定要溫的 topic。那你在溫習時,就可以重點出擊。

溫習特定 topic = 溫習課文 + 做特定 topic 的 pastpaper

Hacker 3

.

The Jargon File has had a special role in acculturating hackers since its origins in the early 1970s. Many textbooks and some literary works shaped the academic hacker subculture; among the most influential are:

* Hackers: Heroes of the Computer Revolution, by Steven Levy
* Godel, Escher, Bach, by Douglas Hofstadter
* The Art of Computer Programming (TAOCP), by Donald Knuth
* The Mythical Man-Month, by Brooks
* Compilers: Principles, Techniques, and Tools (“the Dragon Book”), by Aho, Sethi, and Ullman
* Structure and Interpretation of Computer Programs (SICP), by Abelson and Sussman
* The C Programming Language (K&R), by Kernighan and Ritchie
* The Hitchhiker’s Guide to the Galaxy, by Douglas Adams
* The Tao of Programming, by Geoffrey James
* The Illuminatus! Trilogy, by Robert Shea and Robert Anton Wilson
* Principia Discordia, by Greg Hill and Kerry Thornley
* The Soul of a New Machine, by Tracy Kidder
* The Cuckoo’s Egg, by Cliff Stoll
* The Unix System, by Stephen R. Bourne
* Hackers & Painters, by Paul Graham
* The Cathedral and the Bazaar, by Eric S. Raymond
* The essays of Richard M. Stallman (many published in Free Software, Free Society: Select Essays of Richard M. Stallman)

[10] “Hacker” here means a highly skilled programmer, not a computer criminal. — Me

The basic difference is this: hackers build things, crackers break them. — Eric S. Raymond

In academia, a “hacker” is a person who follows a spirit of playful cleverness and enjoys programming.
