我其它学科都很好,现在就是感觉化学那些实验很难,太多东西了,而且很多知识点都是老师上课做实验时说一下就带过了,书上也没有做题时发现实验这块很多题都不会,比如用 高锰酸钾制取氧气为什么要先取出导管再熄灭酒精灯这种题啦,感觉化学题都是一些记的,不向物理题那样就算难努力想也可以想出来,化学那些性质啊还可以,但我就怕使用仪器这样的题化学题老师不给你说根本就不会,到底该怎么办啊。

为什么大家说数学实验班提优训练难,我做起来却感觉和老师要求的启航新课堂一样简单。可我却不会做新方法 其他回答2113的人都没搞懂人家问的5261什么问题,正巧我知道这几本书,总体上4102黄东坡的新方法是应付低层1653次竞赛或者对付学科特长生的,超级课堂这个书不错,可以作为解题套路范本,并夹杂部分竞赛题,实验班提优训练确实比一般同步教辅参考书要难,如果你能完全搞定实验班提优训练,考个重点高中没什么问题。?
数学课外辅导的题目有必要全做吗
