翰林学院Alevel Chemistry化学辅导

A-Level Chemistry化学课程

A-Level化学课程的设置包含三大块面:物理化学、无机化学和有机化学,并对学生动手操作实验的能力有一定要求。英国高中阶段的化学课程对学生的学科理解有一定挑战,主要的难点包括但不仅限于背诵内容多、语言要求高、有机化学不入门以及实验操作困难,不会写结论。实际上所有的难点在化学这门课可以总结为两个原因:一、学习过程中知识体系建立有疏漏,根基不扎实;二、学习方法不正确导致迟迟不能入门。只要从一开始选对方法,化学的学习会比其他学科更加充满乐趣。化学专业除了是申请化学、生物、医药类专业必修课之外,也是所有理工科类专业非常看重的一门成绩。
