DSE MATHS：中四常規課程 Vol 2 - Equation of Straight line, Four Center (直線方程、四心)

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.

gary sir 教既skills對考試好有幫助

教得幾好有好多學校冇嘅skill講嘅都幾好但係我已經有啲唔記得之前學嘅嘢所以可能有時要重溫一下。cal機嘅用法都講咗好多，但我目前就未完全掌握晒！我會努力掌握返嗰啲技能㗎啦能！Gary好好！

the lesson content was filled with lots of information and many useful tips

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

Gary sir在課程教授了很多不同題型的答題技巧，我在某些題型不是出色，Gary sir可以幫我handle到，加上Gary sir的回覆速度很快，我經常有不明白的題目，只需兩天已經有解题，非常出色。

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。
