看來博士兄就是好艾力度口中的聰明懶惰型[]
咁有無神人分享奪A心得...係咪果d奧數神先A到
回想小學都有份玩奧數,但無心向學,全滅[]
我係 被迫無時間溫書型 。
成個中六淨係做幾件事：做功課(esp Lab report)，搞活動，參加比賽。
都無時間溫書 -.-
中七又泥個 CA Project，整o左我幾個月，成個 e-class 差唔多寫好，
跟住因為我係自修，對佢ｄ要求又唔太清楚，份 proposal 唔夠人砌，全班第四，真衰
D人用 Dreamweaver，而我真係落手落腳打 code －．－
你會留意到 其實考來考去都係哥幾招
例如，MATRIX最尾好鐘意叫你估
In my opinion,most questions (approximately 7XM) in pure paper are those which u have seen before.The remaining marks maybe quite difficult to most of the students,and that's the difference between A and B.
e.g.this year paper 1 polynomial LQ...(part a and d):lol
當我遇上一大堆好亂ge數字就會好易計錯數
e.g. amath的circle,有時會寫到好長好長,好易計錯
應該點解決呢個問題[]
我都好易計錯數
pure個curve skecthing果度我d 兩次通常都錯
system of linear equations 又係成日計錯
我都想知有咩方法可以解決成日計錯數既問題
PURE MATH重視STEP,基本上都好少機會計錯,記緊寫完一個STEP後CHECK一CHECK
CURVE SKETCHING宜LOG左再D,D完後FACTORISE番個FIRST DERIVATIVE,方便SENCOND D,又方便搵SPECIAL PTS
SYSTEM OF EQUATION記住DETERMINANT唔好諗住心算,9成會錯,慢慢搞應該好易掂
各理科人預習成點
我見有d人話睇晒2本physical同organic
但我physical 1都只係去左1/4...
phy mechanics都只係去左1半[]
pmath直頭無預習過,因為佢係印notes,無書買...
比人拋離咁遠,再咁落去莫講話3A...3C都算超額完成了[]

你個d 法同我一樣
不過我考試咁d 比我老師鬧...sosad
話我呢個方法唔夠嚴謹
不過AL d 野無step 分
用咩方法d 都無所謂
d 野有兩招
skill 1
Find d/dx [( x^2 + x + 1 ) / x + 1]
做呢種題目時一定要做左long division 之後先d
skill 2
take natural log and then d (as said by 3A god)
至於System...我只能講
有programme check 數.....(自己參透)
phy睇晒 以無聊可以形容全書
pure mth好難明..........
剩低o個科到底AL chem定applied好呀[]
到而家都未有人比意見我
聽講話AL phy只出1 dimension 的relative velocity...
咁過河問題又算唔算out-C[]
AL Applied Math會令人好痛苦
