Concepts are explained clearly. Useful formula is used and well demonstrated. If you used them correctly, the difficult questions can be solved in a quicker and easier way. Question banks provides a lot of DSE type questions for me to do. Some of their types are repeated and may make you bored. But after drilling a lot, you may not do the careless mistakes anymore. Recommend.

第二期我學咗直線同埋四心嘅題型，亦入咗三個program，當中嘅直線、Area of triangle、四心program超幫到手，幫我慳咗好多時間去做數。同埋Gary sir 講解得好清楚，讚！

Mr Gary teaches the topics very clearly, mention important points, also reminds us about areas which we may make mistakes easily. There are also many calculator program s for each topics very useful and helps us to do questions more quickly.

有教到新嘅program, 同埋點樣應用，仲有計數機嘅內置功能點樣應用，真係好實用，題目都可以做得快啲。上堂嘅時候又會教唔同類型嘅題目，又會俾時間我哋自己做下

阿Sir講得好清楚👍🏻👍🏻👍🏻而且講得簡單易明，所以我非常滿意，仲有阿Sir 講咗好多學校冇教過嘅技巧，做題比之前快好多！！所以如果想攞到更加高分嘅成績就嚟參加啦！！

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。
