IMO(国际数学奥林匹克竞赛)试题的难度是相当高的,主要面向具有出色数学才能和扎实数学基础的中学生。试题不仅涉及的知识点广泛,包括代数、几何、数论、组合数学等多个领域,而且题目设计巧妙,需要参赛者具备深厚的数学素养和灵活的思维能力。
具体来说,IMO试题的难度主要体现在以下几个方面:
1.知识点深度:试题往往涉及高中数学甚至大学数学的知识点,要求参赛者对这些知识点有深入的理解和掌握。
2.思维难度:试题往往不是简单的计算或应用问题,而是需要参赛者通过逻辑推理、创新思维和问题解决能力来找到答案。
3.时间限制:参赛者需要在规定的时间内完成多道题目,这要求他们不仅具备扎实的数学基础,还需要具备快速思考和应对压力的能力。
因此,对于大多数中学生来说,IMO试题的难度是非常高的。然而,这并不意味着普通学生无法参与或享受数学竞赛的乐趣。通过参加各种数学竞赛和培训活动,学生可以逐渐提高自己的数学素养和思维能力,为未来的学习和职业发展打下坚实的基础。
需要注意的是,数学竞赛的目的并不仅仅是选拔出最优秀的学生,更重要的是激发学生对数学的兴趣和热爱,培养他们的数学素养和综合能力。因此,无论学生的数学水平如何,都可以尝试参与数学竞赛活动,体验数学的魅力和挑战。
CMO是超越IMO的存在。因为中国集训队34人随便6人保证IMO团队第一,所以每年CMO的选拔题都比IMO难。而联赛是为了选拔省级优秀竞赛生,根本不是一个档次…联赛题大部分不超纲,CMO没有不超纲…像反演一类的联赛禁用,而CMO随便用…
信息学奥赛考的是pascal或者c,c++,初赛考一些基础知识是笔试,复赛上机,4道题,一道100分。
信息学奥林匹克竞赛旨在推动计算机普及的学科竞赛活动,重在培养学生能力,使得有潜质有才华的学生在竞赛活动中锻炼和发展。
全国青少年信息学奥林匹克联赛(National Olympiad in Informatics in Provinces,简称NOIP)。初赛在每年的10月,复赛在每年的11月。省级联赛分为两个级别:普及组和提高组。
不是。也有填空、实验、简述等形式的题。
刚高一竞赛不会太难,但是竞赛,应在0.5左右!
以往年的联赛通知来看,主要考察的学科及比例如下:
1. 细胞生物学、生物化学、微生物学、生物信息学、生物技术 25%
2. 植物和动物的解剖、生理、组织和器官的结构与功能 30%
3. 动物行为学、生态学 20%4. 遗传学与进化生物学、生物系统学 25%
每年最终的比例可能会有所调整,最终分数同样存在变化。

利益不相关,说题好或者不好只代表个人观点,不喜勿喷,喷就是机构利益相关的小伙伴吧.
胡波提网上有一堆,虽然很多人说不好,但是还是很有可取之处的,有机可以直接扔掉,不过那些计算(虽然有些题数据有问题)是真的很练人的,建议挑一些做做,毕竟好得到,而且你如果在学习元素的时候配上胡波元素也是可以的,是学习辅助的一部分。
还有就是有些题,可以从相关QQ群中获得。总结为
COBP(画图)、Chemy、hcho、xcho、北斗题、吧赛题、各种机构题。
质量比较高的:hcho、Chemy、画图30届和31届,前几届吧赛题,还有xcho的一部分
各种机构题里边,北斗的题目来讲有的时候是比较好的,但是绝大多数时候给我和我同学的印象是偏难怪,比如某年寒假我们去北斗三次考试整个都是生化啊,出题人就是个学生化的...没有啥意义,但是呢,你还是要做一做的(其实看一看知道他是怎么回事就行了,功利性押题),万万万万一押中了题呢?(毕竟以前貌似中过),但是这种题花钱买....买肯德基麦当劳星巴克必胜客哈根达斯吃他不香吗?打游戏氪金他不好吗?你买北斗题?!!但是你要是听教授讲课,还是要首选北斗,注意不要买宾馆的饭票!!!
北斗题目打分:1/10,北斗课程打分:8/10
培尖教育的题,质量比较高,出题人大多数是国家集训队选手,而且是刚结束竞赛的同学,他们可以很好的把握竞赛的方向而非更加偏向自己的专业(像刚才说的生化老师都上大四了...)
培尖题打分:7/10,培尖课程打分:8/10
hcho的题,原来是一个老学长一个人出的,可能风格偏向单一,后续了解到题目也是请很多刚参加完竞赛的同学出的,相比之下思路比较广,这个比较广相比于上述培尖教育的广体现在一张卷子上的各个题目出题人不同,可以更好的模拟国初,至于决赛题,还是得去别的机构啦。
hcho题打分:8/10,hcho课打分:8/10
Chemy题打分:8/10,课我没去过.
xcho题打分:6/10,课我没去过.
剩下的就是非赢利性机构的题啦
画图题:7分,吧赛题:6分。思路都很好,也比较新颖。都是经典。
