2020年9月PAT甲级满分必备刷题技巧

客官°小女子只卖身不卖艺 2023-07-04 03:27 53阅读 0赞

2020年7月的考试结束了，除了本次的考题更新，短期内不会更新。

【7月题目的特点：首次线上考试，没出链表、树相关的模板题，第2到4题背景新颖，大大降低了抄袭历年代码的可能性，可以看作是线上考试的新趋势。不过本次的考点除第四题外也是旧考点，近三年真题也有见过。】

备考的过程对很多人是一件辛苦的事情，请加油，请相信希望的曙光就在眼前。

## 1 分类刷题，刷出水平   1.1先刷最近三年的分类真题1131到1171 ##

Q：为什么要先刷后面这36题？  
A：因为这才是最接近未来考题的题目，刷下来你会发现很多知识点会反复出现。另外，前面题库的题不少超纲，这跟2016年底（我估计的）的时候发布了新的考纲有关。

Q：为什么要按这个顺序刷？  
A：这个顺序是从易到难的，并且是按类型分的，既适合之前按顺序刷过题但是练手还不够的选手，也适合新手。

Q：去哪里提交我写好的题目呢？  
A：题号1131-1155能从甲级题库里找；题号1156-1167，要是想省钱就先看我的题解的题目自己写，等写好了再花点钱到教育超市买，买一次只能生效三小时，逢重大节日可能有六折七折，陈越姥姥会预告的。

Q：如果觉得题目是英文的不好理解，有概念不熟悉、解法不好想到，或者代码不好写，老出BUG，心情好难过的情况怎么办？  
A：如果是差在了知识点，就去补知识点；如果没思路，就去看别人的题解然后独立写，总结坑点，可以说80%真题的情况都可以用老套路应对，努力去做定有收获；如果有bug过不了，就写点测试检查一些，要是太久了都没ac就按别人的思路重新写，不要死磕；如果没状态，就先睡一觉吧。

## 1.2 然后再刷分类题库1001到1131（另外开帖） ##

# 2 刷题总结 站得更高 #

独立练习之余，也得通过自己的总结巩固所学，用技巧与坑点搭建坚固体系。

## 2.1 考前专题复习（已经开始更新） ##

## 2.2 [PAT甲级数据结构类技术总结（完结）][PAT] ##

# 3 彩蛋 #

1.有时候想到之前有个知识点但是也不知道在哪一题的，可以在csdn博客里搜索关键字得到。

2.[liuchuo][]的代码最好读，是仔细打磨过的代码，简介明了，想大家推荐。我也是在模仿这种风格，这里要向她和其他前辈致敬。  
如果也有喜欢参考她的代码的同学，肯定会发现我一般也是用她用过的函数来写代码的。

3.一幅励志漫画：
