the lesson content was filled with lots of information and many useful tips
the teacher taught the different concepts and included lots of interactive teaching methods
the explanations given by the teacher were also very detailed, elaborate and easy-to-understand
materials were also shipped before the lesson started
the materials consist of many questions that are useful and commonly seen
all of this was received at a fair price! would definitely recommend it to everyone :D

Mr Gary provides a lot of useful information for me such as how to use the questions bank, the way to practise the topic questions with the time setting. All the information are seldom discussed in my school and I know little about DSE math exam. The concepts are clearly presented and well organised. Enough homework and exercises are assigned after each lesson. I can monitor my progress in a clear way. Highly Recommended.

極度推薦Gary Sir給將要應付DSE的各位香港學生。
Gary Sir自家獨特計算機program極之好用，無論是卷一或者卷二，完成題目速度都比傳統日校老師所教的方式快捷。

原本學校test嘅MC，10題都會錯至少3題，同埋我最唔熟同本身最驚嘅topic就係exponential同log，但上左呢個course之後，基本上一睇題目就知佢想問咩，答啱嘅都多左好多！

我係第一次參加 regular嘅數學課程，整個課程畀我嘅感覺係值得join嘅。原因係因為Gary Sir 教得好仔細、課後又會問番我哋學成點，真係會畀到我動力去做數！

我覺得Gary sir 講得好好，清曬我以前唔識/搞錯咗嘅concept，都令我喺做卷嘅時候唔會再嘥曬啲時間，可以用唔同嘅技巧同program加快做卷速度，節省時間。

阿sir教得幾好，同埋都會等同學提問問題，答問題時亦很仔細，最後再確保同學是否真的明白，亦有開設telegram group 提供past paper.

課堂講解十分詳細，亦能從中學到很多小技巧，得知原來做一題mc可以通過簡單的sub數然後撳cal機就能得出答案！

Gary Sir 教啲野全部都好實用，完全係超出預期，非常滿意！除此之外有唔明嘅題目去問Gary Sir 佢都會好詳細咁解釋返!

教得十分十分十分之好, 因為可以識到好多平時老師上堂冇教到的東西, 對考試十分十分十分之有幫助。
