Past papers 2

“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 be used for tackling other public examinations.

A:你有沒有按年份做 pastpaper(歷屆試題)?

KWY:我有按 topic(課題)做 pastpaper。我有做已溫習了的 topic 的 pastpaper。我打算溫完書後,才開始按年份做 pastpaper。

A:可以。這樣可以。但是不要太遲。例如,你打算按年份做十年的 pastpaper 的話,其實是要花很多時間的。

LKF:哪應該是集中先把一個 topic 溫完,才溫下一個 topic,還是一開始就分散溫比較好?

A:分散溫。主要應該用按年份做 pastpaper 的方法來溫比較好。如果你打算 “溫完” 一個 topic 才溫下一個 topic 的話,你到會考(公開試)前的一晚,也不會 “溫完” 所有課程的內容。

LKF:但是我已經沒有什麼時間溫 physics 了。 

A:現在,距離公開試只有三個多月的時間,是不會有一段時間,給你特意溫熟某一個課題的。即使有,因為任何一個 topic 都可以無限鑽研,你讀多久,也會覺得不夠熟。哪你如何可以客觀知道自己對某一個 topic 夠不夠熟呢?到頭來,你也是要在做會考題(pastpaper)時,才會知道。

其中一個方案是梅花間竹地按年份做 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,你就可以知道那個 topic,正正就是你特定要溫的 topic。

Hacker 2

.

* Creating software and sharing it with each other
* Placing a high value on freedom of inquiry; hostility to secrecy
* Information-sharing as both an ideal and a practical strategy
* Upholding the right to fork
* Emphasis on rationality
* Distaste for authority
* Playful cleverness, taking the serious humorously and their humor seriously

The difference between hackers and crackers, according to them, is that where hackers use their skills and knowledge to learn more about how systems and networks work, crackers will use the same skills to author harmful software (like viruses, trojans, etc.) and illegally infiltrate secure systems with the intention of doing harm to the system.

「hacker」們建設,而「cracker」們破壞。

真實的黑客所指主要指的是高級程式員,… 而不是為人所誤解專指對電腦系統及程式進行惡意攻擊及破壞的人。
