数学是考研中,决定能否上岸的关键科目。特别是西南交通大学有数学+英语的双科线。对于数学这一块复习的过程中建议分层复习,首先梳理出常考的知识点,基本每年都会考到的知识点,例如解答题中的:求极限、求微分、求偏导、求定积分、求极值、定积分应用、二重积分、微分方程。这些题基本每年必考,看上去似乎不难,但是在考试中很多同学会在这些题上丢分,导致最后数学总分不过百,无缘复试。前期复习一定要把这些题全部拿下,这样考试时,基本可以保证数学总分在100+。</p><p></p></div><div

前期基础阶段,边复习边做做习题集上的基础部分。进入强化阶段后,建议先做5-7年左右的真题,感受一下真题是怎么考的,自己复习的是否和真题一致,自己关注的重点是否是真题考查的重点,然后根据真题针对性的查漏补缺。真题中的考点是每年考查的重点,要以真题为导向。很多同学认为,从头开始把习题集做完就可以了,首先很多同学没有时间把一本习题册做完,其次,高数题目仅做一遍没啥效果,一般做三遍才有效果,但是所有的题目做三遍时间又不够。所以可行的办法就是,挑有质量的题反复做,什么是有质量的题,与真题接近的题。</p><p></p></div><div

0px;text-decoration-style: initial;text-decoration-color: initial" data-from-paste="1"> 比如,数二对行列式计算的考查,喜欢考抽象型的行列式计算,那么数二的同学在复习行列式的计算时,抽象型的行列式的计算要高于数字型行列式的计算。数一喜欢考数字型行列式计算。再比如,线性方程组这块,考研主要是以计算题为主,选择填空考查较少,那么在复习的时候,线性方程组的计算题优先级就高于选择填空。</p><p></p></div><div

0px;text-decoration-style: initial;text-decoration-color: initial" data-from-paste="1"> 同时,除了习题集,还可以做做各个老师出的近两年的压题卷、冲刺卷。比如23考研的同学,可以做做22、21年,各个老师出冲刺卷、押题卷。一般来说,往年押题卷的质量比这个老师出的习题集的质量高</p><p></p></div><div class="index-module_textWrap_3ygOc index-module_newStyle_lg-fl "><p></p><p

建议每两周把自己的笔记过一遍,该记的公式提前记,做过的题也要经常复习,数学题一般是要重复三遍才有效。做一遍可能只是有个模糊的印象,再次遇到还是不会。知识点和重点的题目一定要反复。对于计算能力的训练,可以跟跟杨超老师的三大计算课程,这个有公开免费的。</p><p></p></div><div class="index-module_textWrap_3ygOc

考研数学对计算能力是有一定要求的,四大计算一定要掌握好,求极限、求微分、求微分方程、求积分。你会发现,解答题要想得到最后结果,往往需要算一个积分或者微分方程,如果计算能力不过关,很多题就只能做一半,得不到全分。算错算不出来,是每年丢分的重灾区。很多同学考完,都会感慨,这个题我会做,就是算不来,对不起,算不出最后答案,得分将大大折扣。</p><p></p></div><div
