附：北大学霸整理最全的高三复习计划

重要提醒1：第一轮复习（9月-3月初）基础能力过关

第一轮复习要全面阅读教材，查漏补缺，彻底扫除知识结构中理解上的障碍。在这

一基础之上，对各科知识进行梳理和归纳，使知识系统化。同时配以单元训练，提升应

用能力。

这一轮复习的目标是查出所有理解上的障碍，为全面而准确地记忆打下可靠的基

础。不论平时多么熟悉课本，都不能省略全面阅读教材这一环节。一般而言，考生的复

习障碍主要有:概念不清、公式不会运用、计算不准、原理模糊等等。这些都是理解的

障碍，同时也是记忆的障碍。

考试时，往往使储存在大脑中的知识难以提取出来。通过全盘的通读，才能对信息

进行记忆编码，分类梳理出知识点，才能明白各学科的内在联系，形成系统知识网络结

构。复习完一个章节，就在不看课本只看笔记的情况下，把课本中的知识点一一地过一

遍。遇到记不起来的地方或理解得不是很透彻的地方，再翻开课本看看，这样就会加深

印象和巩固记忆。一轮复习一边是高中三年课程的回顾，一边是知识遗漏的查找，这也

是为高考总复习知识系统化、能力化做好准备的时期。高考是考三年的内容，而在高一

高二落下的知识很多，而高考的其中的一个黄金定律“8020法则”，就是指高考试题的

80%是基础知识，20%是稍难点的综合题，把这部分的基础做好的话，就可以上一所不错

的大学。所以必须把这两年的基础知识补上，避免高考时这些知识变成失分点，自己通

过做大量的题来找漏洞效果不明显而且又浪费了时间。最后以致于信心受挫，决定放弃

学习了。这是学习中的最可怕的现象。我们做题不贵“多”而贵“精”。应该做囊括高

考的重点、难点、考点的题和通过对照老师讲的具体内容检测出漏洞。

重要提醒2：第二轮复习（3月初-5月中）综合能力突破
