家長最常問到的問題：國中理化需要補習嗎？高中物理、化學需要補習嗎？還是家教比較好？詳細差別請參考這篇：國中理化/高中物理化學內容差別 答案視每個孩子的狀況而定。若是要養孩子成為奧林匹亞國手或是進入明星高中資優班，那與一般考國中會考的學習方式是截然不同的，所需要的補習班或是家教，也不會是同一種類別。 chemistry 補習 ，在段考、模擬考、會考拿到好的成績，是不一定要補習的。即使進入高中，也不一定因為難度加深就必須補習或是請家教加強。仍是以學習目標為主。主要分為三種：考好段考採推甄的方式上大學，或是考好學測，或是自然組指考。還好大部分補習班都提供各種目標的一條龍學習資源，不會說一種補習班只適合一種目標。家長與孩子需要從中選擇的即是資優教育或是升學考試。
