差少少上level4 應該點樣最後衝刺 應該all in邊part
利申paper2差開仲要讀material chem 同埋本身indus chem差開
material chem真係難講 全香港得5%考生揀material 果題
唯有可以練同背既野呢幾日儘量做好
例如unit cell計coordination number, number of atom, liquid crystal原理,比較polymer熔點硬度果d
industrial chem多d做reaction order,例graph (order / maxwell / energy profile)
宜家係咩應該操呢啲同埋paper1唔熟既topic?
