9 月 Digital SAT 詳細解析： 這場真的比較簡單嗎？該不該報考？

每次 Digital SAT 考試結束後，學生之間總會討論：這次到底是比較簡單還是比較難？根據 AEI 團隊的第一手分析與考生回饋，答案非常明確——是的，9 月的Digital SAT 整體比 8 月與 6 月場次要簡單許多。

英文科目解析

這次的英文模組有幾個顯著特色：
  • 題目重複：至少有五題直接來自美國 8 月份的 SAT，對部分學生來說算是額外優勢。
  • 沒有引文證據題：以往常見、難度偏高的 Quotation Evidence 題型完全消失。
  • 修辭綜合理解 (Rhetorical Synthesis)：數量明顯增加，而且大部分相當簡單，僅有一題較有挑戰性。
  • 邏輯完成題 (Logical Completions)：通常需要細心推理，但這次出得意外簡單。
  • 字彙題 (Words in Context)：難度不高，正確答案包括 reproducible、forecast、integral、subdued、proxies、substantiated、exhibits。錯誤選項則有 observable、beneficial、harbinger、emissary、monitor。
  • 篇章結構與功能題 (Text Structure & Purpose)：是整份英文考卷中最具挑戰性的部分，答案選項差異極細，必須抓準細節。
  • 圖表題：有些極為簡單，但也不是全部。
  • 文法題：許多「邊界題」(Boundaries) 都是 從屬子句 + 逗號 + 獨立子句 的形式；還有一道題目要求學生辨認問句與陳述句的差別，算是比較少見的考點。
  • 閱讀細節：雖然 attribute/attributed to 沒有出現在字彙題，但卻多次出現在閱讀問題中，測試學生對抽象表達的理解能力。

AEI 的觀察：

這份英文考題的整體難度確實偏低。只要學生具備基本的修辭邏輯感和文法基礎，大部分題目都能輕鬆拿分。真正具挑戰性的地方只出現在篇章結構與功能題，需要對細節高度敏感。

數學科目解析

相較於 8 月與 6 月，9 月的數學考題也顯得更簡單。

整體趨勢：

  • 圓相關題目與聯立方程式題目減少。
  • 著重在 三角形與角度：包含同位角、全等三角形，以及三角函數互補角的關係sin(x)=cos(90o-x)。
  • 再次出現來自美國 8 月份的舊題。
  • 聯立方程式與絕對值題目皆可用 Desmos 快速解決。
  • 最難的部分主要來自統計題。

模組 1 中間的陷阱題

有一道出乎意料的因式分解題出現在模組 1 的中段：
x4+8ax2+16a2-25
題目要求找出哪個選項是它的因式。這種題型通常會被放在模組尾端，但卻突然出現在中間，對部分學生造成心理干擾。

精選數學題目

1. 圓與切線題

已知圓心與切點座標，以及切線 t 的斜率為 10/7，題目問：切線還會經過哪一個點？

  • 由於斜率為正，可立刻排除部分選項。
  • 最後必須將座標代入切線方程式，驗證 C 或 D 才能得到正確答案。

 此題測試的是「理解幾何性質」與「代入驗證」的結合。

2. 長方形與正方形題

一個長方形的長度為寬度的 18.5 倍，且由多個正方形組成，總面積為 74A。已知長方形的長為，求 x。

此題考驗學生的代數與幾何轉換能力，需要靈活運用平方根與面積關係。

3. 統計題

 一組資料有 10 個數：

  • 前 9 個數的平均數為 44。
  • 全部 10 個數的平均數為整數。

題目問第 10 個數是多少。 這其實是 College Board 過去出過的「經典題」，測驗學生是否能利用平均數與總和的關係，並檢查整除條件。

AEI 的觀察：

9 月的數學題型更偏向幾何與三角，代數難度降低。
對於目標滿分的學生來說，關鍵在於：
  • 迅速解決簡單題，爭取時間。
  • 專注檢查統計與因式分解等陷阱題，避免在少數難題上失分。

 

 

in conclusion

那麼，9 月的數位 SAT 真的比較簡單嗎？
是的。 無論是英文還是數學，9 月份考試的整體難度都低於 8 月與 6 月。
英文部分大量出現簡單的修辭與邏輯題；數學則以幾何與角度為重點，刪減了高難度的聯立方程式與圓相關題。
但要注意：考題簡單並不代表分數一定會更高。由於大部分學生都能拿到更多分數，競爭會更加激烈，分數常態分布下的頂尖分數線可能會被拉高。

AEI 建議：

  • 持續熟悉 College Board 的官方題型。
  • 加強細節敏感度（英文的篇章結構、數學的統計題）。
  • 練習快速又正確的解題流程，確保在考場上能保持穩定發揮。

AEI在這裡幫各位整理了八月跟九月SAT的難度比較。作為考生，你應該考哪一場? 以前沒有九月份考試，所以以後九月都會比較簡單嗎?

1. 作為考生，應該考哪一場？

如果你是 高二或高三正在衝刺的學生：
  • 9 月場：2025 年的 9 月 SAT 確實比 8 月、6 月簡單，許多題目直觀、字彙不刁鑽，數學題型也偏基本。對於想先考一個好分數「墊底」、降低心理壓力的學生來說，9 月是一個不錯的選擇。
  • 8 月場：通常 8 月場參加的學生人數多，題目難度偏中高，對於已經準備充分、希望搶先一步提交分數的學生，8 月場仍然很有價值。
  • 建議策略：很多學生會 8 月 + 10 月或 12 月 一起考，因為 College Board 的分數選擇權（Superscore）讓你只需要送出最好的分數。

2. 9 月 SAT 會不會一直比較簡單？

這一點不能直接假設。
  • 2025 年是 第一年開放 9 月考場，今年的試題確實明顯比 8 月、6 月簡單。
  • 但 SAT 的設計邏輯是 分數常態分布，也就是說：
    • 題目簡單 → 更多學生高分 → 曲線更嚴格（頂端分數更難拿）。
    • 題目困難 → 更多學生失分 → 曲線寬鬆（頂端分數反而較好拿）。
  • 因此，9 月「容易」不一定等於「更好拿高分」。實際上，有時候難的考試反而更有利於目標 1500+ 的學生。

3. AEI 的觀察

  • 不要單押 9 月場：雖然 2025 年的 9 月確實偏簡單，但未來不一定會維持這樣的趨勢。College Board 很可能調整題目難度。
  • 最安全的策略：建議學生至少報名 兩場考試（如 8 月 + 10 月，或 9 月 + 12 月），這樣即使其中一場出現失誤，也有另一場補救機會。
  • 高分衝刺生：如果你目標是 1550–1580 甚至滿分，題目「難一點」的場次（像 8 月）有時候反而更划算，因為曲線會更寬。

結論：

  • 9 月 SAT 在 2025 年的確比較簡單，但這並不保證「分數更容易高」。
  • 考生應該把 9 月視為一個 額外的機會，而不是「保底場」。
  • 長遠來看，還是要安排多場考試，把握 Superscore 優勢，確保送出最理想的分數。

 

September Digital SAT: Should I take the September Test?

Each Digital SAT date comes with its own level of difficulty, and students often ask whether September is easier than August or June. Based on AEI’s first-hand analysis and student feedback, the answer is clear: Yes, the September Digital SAT was noticeably easier compared to other administrations this year.

 

English Section Analysis

The English modules stood out in several ways:

  • Recycled Material: At least five questions were reused directly from the USA August 2025 test.
  • No Quotation Evidence Questions: A common stumbling block was absent entirely.
  • Rhetorical Synthesis: Numerous and straightforward, with only one tougher example.
  • Logical Completions: Easier than usual, with very direct logical flow.
  • Words in Context: The tested words were accessible. Correct answers included reproducible, forecast, integral, subdued, proxies, substantiated, and exhibits. Wrong-answer traps included observable, beneficial, harbinger, emissary, and monitor.
  • Text Structure & Purpose: These were among the most difficult in English, with answer choices hinging on very subtle distinctions.
  • Graphs: Some chart-based questions were very easy, though not all.
  • Grammar: Many Boundaries questions involved the pattern dependent clause + comma + independent clause. One question asked students to identify the difference between a question form and a statement form—an unusual test point.
  • Reading Notes: While attribute/attributed to was not a Words in Context question, it appeared repeatedly in reading questions, testing students’ ability to parse abstract phrasing.

AEI’s Observation:
 The September English section rewarded students who were strong in rhetorical flow, precise detail-reading, and foundational grammar. Vocabulary was forgiving, synthesis questions were giveaways, and the only real challenge lay in the detail-oriented Text Structure/Purpose items.

 

Math Section Analysis

Overall, the Math section was easier than usual, with many students reporting it felt significantly smoother than August or June.

General Trends

  • Fewer circle problems and fewer systems of equations than usual.
  • More emphasis on triangles and angles: alternate interior angles, congruent triangles, and trigonometric identities like the sine/cosine complement rule  .
  • Several questions were repeated directly from the USA August 2025 SAT.
  • Systems of equations and absolute value problems were solvable with Desmos.
  • A few tricky statistics problems stood out as the hardest.

A Notable Middle-of-Module 1 Trap

An unusual factoring question appeared in the middle of Module 1:

Students were asked which answer choice was a factor. While solvable with algebraic manipulation, its placement caught students off-guard—such a problem usually shows up at the end of a module, not in the middle.

Featured Math Questions

1. Circle & Tangent Question
 A circle with a given center and tangent point was tested. The tangent line t had slope 10/7​, and students were asked which other point it passed through. The key:

  • Eliminate choices A and B since the slope was positive.
  • The problem required actually plugging points into the line equation to verify whether C or D was correct.
     This tested whether students understood slope conditions while still checking details.

2. Rectangle & Squares Question
 A rectangle’s length was given as 18.5 times its width. The rectangle was partitioned into squares with a total area of 74A. The length was expressed as ​.

The task: determine x.
 This was a multi-step algebraic manipulation problem blending geometry and radicals. Students needed to:

  • Translate dimensions into algebra,
  • Use the given area condition,
  • Express the rectangle’s length in terms of A​.

3. Statistics Question
 A dataset of 10 values was presented:

  • The average of the first 9 values = 44.
  • The average of all 10 values = an integer.

Students were asked for the 10th value.

 

This is actually a classic College Board problem from years ago—a nice example of how older material resurfaces. The trap was recognizing that the 10th value had to make the new average an integer, so the 10th entry had to fit the divisibility condition on the total sum.

 

AEI’s Observation

The September Math section was:

  • Easier than usual, with many “straightforward” problems.
  • Emphasis on angles, triangles, and trig basics more than advanced algebra.
  • The only moments where students could stumble were the factoring surprise and the trickier statistics.

For students aiming at a perfect score: success came down to efficiency and precision—getting through the simple problems quickly and having enough time to double-check the handful of tricky items.

 

Conclusion

So, was the September Digital SAT really easier?
 Yes. Both English and Math were smoother compared to August and June. English leaned heavily on easy rhetorical synthesis and straightforward logical completions, while Math emphasized approachable geometry and algebra with only a few traps.

But a word of caution: Easier tests often raise the curve. With many students scoring higher, the competition for top percentiles becomes tighter.

Advice: Students preparing for upcoming dates should keep practicing with College Board material, focus on the high-precision details (like Text Structure in English and statistics in Math), and build the ability to solve both easy and tricky problems quickly and confidently.

AEI has put together a clear comparison of the August and September SAT exams. As a test-taker, which date should you choose? Since September is a newly added test date, does that mean it will always be easier in the future?

1. As a Test-Taker, Which Digital SAT Date Should You Choose?

If you are a junior or senior aiming for a strong score:

  • September SAT: In 2025, the September test was noticeably easier than August or June. Many questions were straightforward, vocabulary was manageable, and math leaned toward basic geometry and algebra. For students who want to get a solid “baseline score” to reduce stress, September was a good choice.
  • August SAT: Traditionally, the August test has more participants, with a medium-to-high difficulty level. For well-prepared students hoping to submit early scores, August is still valuable.
  • Strategy: Many students choose to sit two test dates (for example, August + October or September + December). Thanks to College Board’s Superscore, you only need to send your best scores.

2. Will the September SAT Always Be Easier?

Not necessarily.

  • 2025 was the first year College Board offered a September test, and yes, this administration felt easier.
  • However, the SAT is designed to follow a normal score distribution:

    • Easier test → More students score higher → The curve becomes stricter (harder to reach top percentiles).
    • Harder test → More students miss points → The curve loosens (top scores become slightly more forgiving).

So, even if September feels easier, it doesn’t guarantee a higher score. In fact, harder tests can sometimes benefit students targeting 1500+ since the curve adjusts.

3. AEI’s Observation

  • Don’t rely on September alone: While the 2025 test was easier, future September exams may not stay that way. College Board could rebalance difficulty.
  • Safest approach: Plan to sit at least two test dates. This way, you have a backup if one test doesn’t go as planned.
  • High scorers (1550–1580+): Paradoxically, harder tests (like August) can work in your favor because the curve is more forgiving at the top.
