2016年成人高考(专升本)高等数学公式大全 提高成绩的途径大致可以分为两种：一是提高数学整体的素质和能力，更好的驾驭考试;二是熟悉考试特点，掌握考试方法，将自己已有的潜能和水平发挥到极致。 如果说在复习中，上面两种方法那一种更能在最短的时间内提成人高考试的分数呢？对于前者，是需要我们在整个高中乃至以前的学习积累下来的综合能力，这个能力的提高需要时间和积累，在短期内的提高是有限的;对于后者能力的了解和掌握对短期内迅速提成人高考试成绩的成效是很明显的。而且，在一般的学校教育中，往往只重视前者而忽视后者。我们用以下几个等式可以很好的说明上述两者的关系和作用。 一流的数学能力 + 一流的考试方法和技巧 = 顶尖的成绩 一流的数学能力 + 二流的考试方法和技巧 = 二流的成绩 二流的数学能力 + 一流的考试方法和技巧 = 二流的成绩其实对于考试方法和技巧的掌握，大致包含以下几个方面： 一、熟悉考试题型，合理安排做题时间。 其实，不仅仅是数学考试，在参任何一门考试之前，你都要弄清楚或明确几个问题：考试一共有多长时间，总分多少，选择、填空和其他
主观题各占多少分。这样，你才能够在考试中合理分配考试时间，一定要避免在不值得的地方浪费大量的时间，影响了其他题的解答。 拿安徽省的数学成人高考题为例，安徽省数学成人高考满分为150分，时间是2小时，其中选择题是12道，每题5分，共60分;填空题4道，每题是4分，共16分，解答题一共74分。所以在了解这些内容后，你一定要根据自己的情况，合理安排解题时间。 一般来说，选择题填空题最迟不宜超过40分钟，按照尚博学校的教学标准是让学生在30分钟之内高效的完成选择填空题。你必须留下一个多小时甚至更多的时间来处理后面的大题，因为大题意味着你不仅要想，还要写。 二、确保正确率，学会取舍，敢于放弃。 考试时，一定要根据自己的情况进行取舍，这样做的目的是：确保会做的题目一定能够拿分，部分会做或不太会做的题目尽量多拿分，一定不可能做出的题目，尽量少投入时间甚至压根就不去想。 对于基础较好的学生，如果感觉前面的选择填空题做的很顺利，时间很充裕，在前面几道大题稳步完成的情况下，可以冲击下最后的压轴题，向高分冲击。对于基础一般的学生，首先要保证的是前面的填空选择题大部分分值一定能够稳拿，甚至是拿满分。对于大题的前几题，也尽量多花点时间，一定不要在会做的题目上无谓失分，对于大题的后两
