中五常規課程 Vol 2 - Permutation and Combination (排列與組合)

今期教排列與組合，學校老師教得好求其，係Gary sir呢度我哋可以好簡單咁學到成件事嘅概念，成件事由複雜變得簡單方便快捷，唔洗用日校老師又長又大風險錯嘅爆數同複雜嘅計算方法，只需要記得計數機嘅input 同 output就可以，快而準，每種出題模式都會有幾條問題做，鞏固知識，雖然呢課講真真係幾難，不過多謝Gary嘅清晰教學同耐心，我先能夠完全掌握

已經係第四次報讀laaa 🙈 整體來講，上堂體驗仍然都係非常好！！Gary Sir 會係課堂上講解得好清晰，有好多好有用嘅計數skills，做題目嘅時候都覺得容易咗！而且上堂都會有好多互動，我覺得 Gary Sir 最細心嘅一點係會成日keep住我哋係咪真係明，鼓勵我哋唔明一定要問! 仲有我係做 question bank 嘅時候有好幾條mc、lq 唔識做，Gary Sir 都好有耐心咁逐條解釋比我聽😭👍🏻 推薦大家報讀！！😳💕✨

今期教了nPr,nCr 同埋probability ，我學校之前剩係喺中三教過少少probability ，上完今期後，我對於這些課題都明白了，掌握咗好多，另外Gary Sir亦教得好清晰，教完一題後我可以舉一反三咁做埋同類題目，而且Gary Sir用大

Here is a 50-word comment for your chemistry tutor, TC, praising his teaching in preparing you for your F5 final exam:

TC, your exceptional instruction has been instrumental in preparing me for the F5 final exam. Your clear explanations and emphasis on the key concepts have given me the confidence and knowledge needed to excel. I am grateful for your dedication and the time you have invested in ensuring my success.

gary sir將我平時可能要諗好耐嘅probi題目講解得好清楚，分成唔同題型，容易理解左好多，而家知道做嘅方法同思維，做題目都做快好多，同埋有時課堂幾好笑，唔會覺得悶

今次係第二次買gary sir嘅數學堂，啲筆記全部都好清楚咁list曬每個topic常見嘅題型，上完堂之後就清左concept好多，溫書個陣睇返筆記就會更快記得個課嘅內容！

Gary sir 教咗好多唔同計nCr 嘅技巧同方法，有好多唔同類型的題目俾我地去嘗試，有唔同方法去計同一個問法，可以俾我哋計得快D。

A great course to help get over all the difficulties and misconceptions that occur when handling these two troublesome concepts, permutation and combination. Gary sir effectively teaches different methods to easily combat these questions. he also introduced a wide range of question types.

十分十分十分好, 不但教得十分之有趣同十分之清楚, 另外又可以學到有用的數學知識同考試技巧。
