AIME How do students qualify to participate in the AIME? Qualification parameters for the AIME vary each competition cycle. For the AMC 10, at least the top 2.5% of all scorers on the AMC 10 A and the top 2.5% of scorers on the AMC 10 B are invited to take the AIME. For the AMC 12, at least the top 5% of all scorers on the AMC 12 A and the top 5% of scorers on the AMC 12 B are invited.
AIME floor: Before 2020, only the top 2.5% in AMC 10 and 5% in AMC 12 were invited to participate in AIME; in 2020 and after, the MAA invites more students to take AIME, so the AIME cutoffs are lower than the AMC 10 top 2.5% and AMC 12 top 5% cutoffs. In other words, in 2019 and before, the AIME floor is equivalent to the top 2.5% in AMC 10 and 5% in AMC 12 cutoffs; in 2020, the AIME floor is more like the top 5% in AMC 10 and 5-10% in AMC 12 cutoffs. Not known for sure what will happen to AIME floor in 2021.
想请教接下来一年如何准备，争取下次能进步。他这次初次尝试，准备了将近4个星期，做了十几套过去的考题，通过做旧题学习。近8年的旧题错2-5道。几乎没有学过AOPS，买到intro4本时已经年底了，实在来不及看。他考前manage看了一点数论那本书。大家有什么建议能分享吗？再有他不是牛娃，这个水平还有潜力提高吗？谢谢
現在AMC10也取5%了 不像之前只取2.5% 所以今年cut off只是100出頭
还是要上课学。这里看到不少上AOPS的课，我听有人分享上课的作业特别好，不是书上的题。不知道有没有必要上课学，毕竟不便宜。
考前两个月开始做题？
考成这样，我想他是不是到头了。不过你的意思是学过那4本，应该还会提高。

把書上的也加進去 那早就算幾十套了吧
是不是没有啥潜能了。

AMC8满分了吗？
也许他学学那4本，还有上升空间。
学校不参加。这次能考10也是运气，因为他AlgII在高中上，高中数学老师说能考10，圣诞节前一周得知，娃当时特高兴。
但他做近几年的题一直非常稳定，我们娘俩就开始对分数有期待了。
我家的七年级的时候差一道题，八年级上了一年课考过了
如果不是因为数学比较好，他也许会像他大多朋友一样去学医了而不是学数学。
竟然有一段我要读两遍才搞明白，许是自己太苯了。他说书写的很明白，他一遍就懂了。
也没进aime, 10年级进JMO. 不过话说回来，JMO升学没用，最后也没申请到理想的学校。不过数学有用，现在可以给小娃上课。
2019 AIME1 2730 AIME2 1226
2020 AIME1 4124 AIME2 沒資料
應該可以說2020進AIME的人數多蠻多的
麻省没录取？据说耶律好入数学娃，他们想加强理工科。
哈佛，斯坦福，哥大，宾大不一定热总数学娃。
我娃8年纪考的跟9年纪差不多。我觉得8年纪还有些题不会，挣了1.5分，到了9年纪，以为自己会了，结果还做错了。
每周很积极的回答同学的问题，上课也是积极抢答问题。找到一个组织，挺好的
