机考数学变难，变成动态给题和动态给分，adaptive testing和adaptive scoring，简单的题即使全答对了，也得不了满分，因为给分的时候系统会用weight of difficulty adjust. The SAT’s adaptive design means the system adjusts the difficulty based on performance. However, scoring is also influenced by the difficulty of the modules given. Harder modules carry more weight in the final score. The student’s performance in both modules, especially in terms of accuracy and the difficulty level of the questions they receive, will determine their score. The easiest scenarios will not lead to a perfect score, while a strong performance in more difficult modules can help achieve a higher score.
据说是更难拿满分。
隔壁就别问了，那么优秀肯定是裸考
senior早考的不需要机考吧？我娃11年级也有不少是改机考之前去考了的。
是的，SAT机考大家分数一般都下降一点。不过从统计学意义上讲和以前纸考差别不大。
今年3月份机考，数学题比以前变难，特征是：有些题目如果只用Desmos，将花费极多时间，但如果Algebra 2基础扎实，手算也就分分钟。
现在ACT满分比SAT满分容易几倍。
去年的SAT机考数学完全可以通过刷它家的几套练习题和Suite Question Bank。
今年3月的机考数学，基本题当然还是要刷它家新增的几套练习题，但拔高题不在它家练习题和Suite Question Bank范围内，也不能仅靠Desmos得到快速解答，更像是考察大家Algebra 2真实水平。
今年3月的机考数学，我目前联系到的辅导学生，没有数学800的，不像去年每次都有数学800的。这次SAT数学得了760-790的学生，在我辅导AP Calculus BC以后都能在学校拿A或者B，说明SAT数学760或以上就够用了。有多余的时间不如多参加义工或课外活动。
你这个逻辑很奇妙。首先任何一门课在校内得B都会影响大学申请。其次，用一门SAT不考的内容的数学课来证明760对大学申请够用。 你是不是应该去补补逻辑了
2-3个B根本不影响去U Penn这样的学校。
前年我辅导的一个学生AP Calculus BC拿B，AP Physics C拿B，其它都是A，还是去了U Penn。
我注重各个学科内在联系。如果SAT数学考不好，说明代数基本功不好，肯定会影响微积分学习。一个命题的逆反命题等于原命题。所以可以说如果不影响微积分学习，那代数基本功还行。
