做一次限时模拟考，拿回来的不只是分数，而是一份哪些主题在扣你分的清单。主攻最弱的那一个，再考一次，看着清单变短。四个级别 —— PSAT 8/9、PSAT 10、PSAT/NMSQT 与 SAT —— 让你在真正对应自己年级的位置上练习。
光有分数教不了什么。每一次限时作答都按主题计分，所以结果是一张"该练什么"的清单，而不是一个让人沮丧的数字。
选择与你年级对应的考试。所有级别都取自 College Board 相同的四个领域：Algebra、Advanced Math、Problem-Solving & Data Analysis 与 Geometry & Trigonometry。
PSAT 8/9 的卷子不是把 SAT 的题目减少几道——它们的难度不同，取自各自考试真正涉及的范围。
做错时给你的是完整解法，而不是一个字母。做错的题会再次出现，直到不再做错。
完整套题的时长与真实考试一致，节奏是练出来的，而不是考试当天才发现的。
我们只提供数学部分。Reading and Writing 是另一种能力，教法也不同，做得半吊子比不做更糟。若以 National Merit 为目标，请注意其选拔指数对 Reading and Writing 的权重高于数学——这里能把考试的一半准备好，而不是全部。
与年级对应的那个：八、九年级用 PSAT 8/9，十年级用 PSAT 10，十一年级用 PSAT/NMSQT，十一、十二年级用 SAT。如果觉得当前级别轻松，就该往上走——这架梯子是用来尽早往上爬的，不是用来重复的。
不是。SAT 与 PSAT 由 College Board 命题并组织。我们是独立的练习平台，题目全部自主编写，不使用历年真题。
仅靠这里还不够。National Merit 的选拔指数对 Reading and Writing 的权重高于数学，而我们不涉及 Reading and Writing。我们能做的是让你不要在数学这一半失分。
学校在每年秋季的十月窗口组织 PSAT 各级别，较低级别另有春季窗口。SAT 在全年多个周末举行。日期由 College Board 确定且逐年变化——请向其官方或学校顾问确认。

Every question is written in-house and modelled on the published format and content domains of the digital SAT Suite — it is not past exam material. Our practice covers the Math section only; we do not offer Reading and Writing. National Merit selection uses an index that weights Reading and Writing more heavily than Math, so no practice here can determine that outcome. Test dates, scoring and eligibility are set by the College Board and may change — always confirm current details with them or your school counselor.
