IMO（國(guó)際數(shù)學(xué)奧林匹克競(jìng)賽）試題的難度是相當(dāng)高的，主要面向具有出色數(shù)學(xué)才能和扎實(shí)數(shù)學(xué)基礎(chǔ)的中學(xué)生。試題不僅涉及的知識(shí)點(diǎn)廣泛，包括代數(shù)、幾何、數(shù)論、組合數(shù)學(xué)等多個(gè)領(lǐng)域，而且題目設(shè)計(jì)巧妙，需要參賽者具備深厚的數(shù)學(xué)素養(yǎng)和靈活的思維能力。
具體來說，IMO試題的難度主要體現(xiàn)在以下幾個(gè)方面：
1.知識(shí)點(diǎn)深度：試題往往涉及高中數(shù)學(xué)甚至大學(xué)數(shù)學(xué)的知識(shí)點(diǎn)，要求參賽者對(duì)這些知識(shí)點(diǎn)有深入的理解和掌握。
2.思維難度：試題往往不是簡(jiǎn)單的計(jì)算或應(yīng)用問題，而是需要參賽者通過邏輯推理、創(chuàng)新思維和問題解決能力來找到答案。
3.時(shí)間限制：參賽者需要在規(guī)定的時(shí)間內(nèi)完成多道題目，這要求他們不僅具備扎實(shí)的數(shù)學(xué)基礎(chǔ)，還需要具備快速思考和應(yīng)對(duì)壓力的能力。
因此，對(duì)于大多數(shù)中學(xué)生來說，IMO試題的難度是非常高的。然而，這并不意味著普通學(xué)生無法參與或享受數(shù)學(xué)競(jìng)賽的樂趣。通過參加各種數(shù)學(xué)競(jìng)賽和培訓(xùn)活動(dòng)，學(xué)生可以逐漸提高自己的數(shù)學(xué)素養(yǎng)和思維能力，為未來的學(xué)習(xí)和職業(yè)發(fā)展打下堅(jiān)實(shí)的基礎(chǔ)。
需要注意的是，數(shù)學(xué)競(jìng)賽的目的并不僅僅是選拔出最優(yōu)秀的學(xué)生，更重要的是激發(fā)學(xué)生對(duì)數(shù)學(xué)的興趣和熱愛，培養(yǎng)他們的數(shù)學(xué)素養(yǎng)和綜合能力。因此，無論學(xué)生的數(shù)學(xué)水平如何，都可以嘗試參與數(shù)學(xué)競(jìng)賽活動(dòng)，體驗(yàn)數(shù)學(xué)的魅力和挑戰(zhàn)。
CMO是超越IMO的存在。因?yàn)橹袊?guó)集訓(xùn)隊(duì)34人隨便6人保證IMO團(tuán)隊(duì)第一，所以每年CMO的選拔題都比IMO難。而聯(lián)賽是為了選拔省級(jí)優(yōu)秀競(jìng)賽生，根本不是一個(gè)檔次…聯(lián)賽題大部分不超綱，CMO沒有不超綱…像反演一類的聯(lián)賽禁用，而CMO隨便用…
不是。也有填空、實(shí)驗(yàn)、簡(jiǎn)述等形式的題。
信息學(xué)奧賽考的是pascal或者c，c++，初賽考一些基礎(chǔ)知識(shí)是筆試，復(fù)賽上機(jī)，4道題，一道100分。
信息學(xué)奧林匹克競(jìng)賽旨在推動(dòng)計(jì)算機(jī)普及的學(xué)科競(jìng)賽活動(dòng)，重在培養(yǎng)學(xué)生能力，使得有潛質(zhì)有才華的學(xué)生在競(jìng)賽活動(dòng)中鍛煉和發(fā)展。
全國(guó)青少年信息學(xué)奧林匹克聯(lián)賽(National Olympiad in Informatics in Provinces，簡(jiǎn)稱NOIP)。初賽在每年的10月，復(fù)賽在每年的11月。省級(jí)聯(lián)賽分為兩個(gè)級(jí)別：普及組和提高組。
剛高一競(jìng)賽不會(huì)太難，但是競(jìng)賽，應(yīng)在0.5左右！
以往年的聯(lián)賽通知來看，主要考察的學(xué)科及比例如下：
1. 細(xì)胞生物學(xué)、生物化學(xué)、微生物學(xué)、生物信息學(xué)、生物技術(shù) 25%
2. 植物和動(dòng)物的解剖、生理、組織和器官的結(jié)構(gòu)與功能 30%
3. 動(dòng)物行為學(xué)、生態(tài)學(xué) 20%4. 遺傳學(xué)與進(jìn)化生物學(xué)、生物系統(tǒng)學(xué) 25%
每年最終的比例可能會(huì)有所調(diào)整，最終分?jǐn)?shù)同樣存在變化。

利益不相關(guān)，說題好或者不好只代表個(gè)人觀點(diǎn)，不喜勿噴，噴就是機(jī)構(gòu)利益相關(guān)的小伙伴吧.
胡波提網(wǎng)上有一堆，雖然很多人說不好，但是還是很有可取之處的，有機(jī)可以直接扔掉，不過那些計(jì)算（雖然有些題數(shù)據(jù)有問題）是真的很練人的，建議挑一些做做，畢竟好得到，而且你如果在學(xué)習(xí)元素的時(shí)候配上胡波元素也是可以的，是學(xué)習(xí)輔助的一部分。
還有就是有些題，可以從相關(guān)QQ群中獲得。總結(jié)為
COBP（畫圖）、Chemy、hcho、xcho、北斗題、吧賽題、各種機(jī)構(gòu)題。
質(zhì)量比較高的：hcho、Chemy、畫圖30屆和31屆，前幾屆吧賽題，還有xcho的一部分
各種機(jī)構(gòu)題里邊，北斗的題目來講有的時(shí)候是比較好的，但是絕大多數(shù)時(shí)候給我和我同學(xué)的印象是偏難怪，比如某年寒假我們?nèi)ケ倍啡慰荚囌麄€(gè)都是生化啊，出題人就是個(gè)學(xué)生化的...沒有啥意義，但是呢，你還是要做一做的（其實(shí)看一看知道他是怎么回事就行了，功利性押題），萬萬萬萬一押中了題呢？（畢竟以前貌似中過），但是這種題花錢買....買肯德基麥當(dāng)勞星巴克必勝客哈根達(dá)斯吃他不香嗎？打游戲氪金他不好嗎？你買北斗題？！！但是你要是聽教授講課，還是要首選北斗，注意不要買賓館的飯票！！！
北斗題目打分：1/10，北斗課程打分：8/10
培尖教育的題，質(zhì)量比較高，出題人大多數(shù)是國(guó)家集訓(xùn)隊(duì)選手，而且是剛結(jié)束競(jìng)賽的同學(xué)，他們可以很好的把握競(jìng)賽的方向而非更加偏向自己的專業(yè)（像剛才說的生化老師都上大四了...）
培尖題打分：7/10，培尖課程打分：8/10
hcho的題，原來是一個(gè)老學(xué)長(zhǎng)一個(gè)人出的，可能風(fēng)格偏向單一，后續(xù)了解到題目也是請(qǐng)很多剛參加完競(jìng)賽的同學(xué)出的，相比之下思路比較廣，這個(gè)比較廣相比于上述培尖教育的廣體現(xiàn)在一張卷子上的各個(gè)題目出題人不同，可以更好的模擬國(guó)初，至于決賽題，還是得去別的機(jī)構(gòu)啦。
hcho題打分：8/10，hcho課打分：8/10
Chemy題打分：8/10，課我沒去過.
xcho題打分：6/10，課我沒去過.
剩下的就是非贏利性機(jī)構(gòu)的題啦
畫圖題：7分，吧賽題：6分。思路都很好，也比較新穎。都是經(jīng)典。
