闭组会议总结
今天下午小组举行了闭组会议。先是由两位优秀的正在实习的学姐讲述了她们的实习经历，然后是大家的提问环节，最后是每个方向的负责人总结上学期的学习情况。
通过认真听两位学姐分享自己的实习经历，我受益匪浅。因为无论我们将来是选择考研还是就业，到最后都会去找工作的。两位学姐都提出我们要从大一开始练习算法题，力扣的每日一题就是不错的选择。学姐的建议是先独立思考半个小时，如果半个小时后还没有思路，就可以查看题解。通过对题解的认真研究，学会一道题的多种解法。
我们学校的知名度不够，既不是985、211，也不是“双一流”，因此我们更要提升自己的能力，才能在以后的求职中脱颖而出。在求职过程中，要多投简历，“海投”。在我们投简历时，要在简历中突出自己的能力和自己的成果。这就需要我们平时在小组多做项目，才不至于在以后让自己的简历是一片空白。而且多做项目能让我们复习巩固前一阶段所学知识。不过项目看的不止是数量，更重要的是它的质量。学姐还说到要早日去找实习工作，以便自己能够学到更多东西，积累经验。我们的博客也要坚持写，这在以后都是加分项。
想要学好我们这个专业，高数也是必不可少的。
在各个方向负责人总结时，学长说道，我们的成果并不明显。我觉得这是因为我们还没有找到属于自己的方向，找到自己的方向是非常重要的。“如果没有目标地前进，那么任何方向的风都是逆风。”
虽然小组闭组后，对我们的学习时间要求的没有那么严格了，但是我们也要抓紧学习，复习考试科目，不能松懈自己的学习。期待能够成为更好的自己。
