Digital SAT QAS Breakdown: December 2025 Test (12E) — The Second US Form, Same Ecosystem, New Costumes
Last updated: September 2026 · By the AllSatPapers Content Team
Form 12E is the second complete US form from December 2025 — 98 questions across all four modules, clean readable text, no answer key. It also proves December was a question ecosystem: essentially the entire form surfaces inside the 12F question bank — an overlap of 117.3% of the test, because the bank holds duplicate copies of some 12E items. Same ecosystem, new costumes. Below: real stems from the parsed text, a team-verified answer set, the retune families, and the three questions found nowhere else.

Sample Questions — Quoted From the Parsed Text
Reading & Writing, Module 1, Q1 — Dickens, Straight From the Bank
The following text is from Charles Dickens's 1861 novel Great Expectations… "the wooden finger on the post directing people to our village — a direction which they never accepted, for they never came there — was invisible to me until I was quite close under it." As used in the text, what does the word "accepted" most nearly mean?
Words in context → Answer C: "Followed." A direction is something you follow — and the neighbors "never came there." This question lives verbatim in the 12F bank at R&W M1 Q82, but watch the costume: 12E's choices run Allowed / Changed / Followed / Approved; the bank's run Changed / Followed / Approved / Allowed. Same question, shuffled letters — in the bank the answer is B.
Reading & Writing, Module 2, Q26 — The Great Salt Lake, Asked 12E's Way
While researching a topic, a student has taken the following notes: The Great Salt Lake in Utah is one of the world's saltiest bodies of water. The northern portion of the lake has a higher concentration of salt than the southern portion. Aquatic insects called Ephydra cinerea live in the southern portion. Bacteria called Achromobacter live in the southern portion. The student wants to emphasize a difference between Ephydra cinerea and Achromobacter.
Notes synthesis → Answer B: "Ephydra cinerea and Achromobacter are different types of organisms…" Same lake as 12C's salinity notes — but 12C asks you to contrast the water, 12E the organisms. The notes barely change; the ask does.
Math, Module 1, Q19 — The Evaporation Function, Verbatim From 12C
The function f(x) = 36 − 0.17x gives the estimated height, in centimeters (cm), of the water in the glass x days after the start of the experiment. Which of the following is the best interpretation of 36 in this context?
Answer A: the estimated height of the water at the start (plug in x = 0). This is 12C's Math M2 Q2 word for word — one of five verbatim handoffs between the two forms.
Math, Module 2, Q20 — 12C's System, Retuned
y = 4x and 8x − 9y = −56. The solution to the given system of equations is (x, y). What is the value of x + y?
Answer C: 10. Substitute: 8x − 9(4x) = −28x = −56, so x = 2, y = 8. Compare 12C's Math M1 Q2, which asks for 3x + 8y given 9(3x) ± 7(8y) (answer 43) — same skeleton, every number redressed.
Verified Answers From 12E — Checked by Our Team
No key ships with this form; we solved this working set ourselves — math items exactly from the parsed stems, vocabulary items only where the context is unambiguous.
| Location | Question (abbreviated) | Verified answer |

| R&W M1 Q21 | Tamsin Mather volcanoes — stratovolcano vs lava dome transition | A: "in contrast," |
| R&W M1 Q24 | Stanton and Anthony ______ for women's right to vote | D: "campaigned" |
| R&W M2 Q18 | In 1979, Susan B. Anthony ______ the first woman on a US coin | D: "became" |
| R&W M2 Q19 | Evaluate the ______ of a scholar's research — citation counts | B: "impact" |

Cross-Form Analysis: The Form the Bank Already Knew
Here is 12E's fingerprint against the rest of the archive — verbatim, retuned, and family-level matches as a share of its 98 questions:
| Other document | Verbatim | Retuned | Family | Share of 12E |
|---|---|---|---|---|
| 2025 12F Question Bank | 92 | 23 | 0 | 117.3% |
| 2025 12C | 5 | 6 | 1 | 11.2% |
| 2025 12D | 2 | 8 | 0 | 10.2% |
| 2025 9J Question Bank (September) | 1 | 8 | 1 | 9.2% |
| 2025 8G Question Bank (August) | 1 | 7 | 0 | 8.2% |
| 2025 5E (May) | 0 | 5 | 0 | 5.1% |
An overlap above 100% is possible because the 392-question 12F bank keeps near-duplicate copies of many questions, so one 12E item can match two bank entries. Smaller threads run to November (11A, 11D, 11E at 3–4% each), October (10C, 10G, 10H), and May's 5E. The buyer's takeaway: owning 12F gets you nearly all of 12E's questions, but only 12E preserves them as a real, sequenced, 98-question exam.

The December Retune Map: 12E's Families, Verified
Our 12C breakdown mapped December's shared question families; each 12E branch below was verified against this form's actual text:
| Question family | Where in 12E | 12E's version |
|---|---|---|
| Hidalgo municipalities (notes) | R&W M1 Q5 | Tlahuelilpan: 17,153 (2010) → 19,067 (2020) |
| Hours worked 1950–2017 (econ data) | R&W M1 Q8 | Netherlands, −564 hours vs Denmark's −649 — verbatim in the bank (R&W M1 Q84) |
| Apollo Moon sensors | R&W M1 Q16 | Obsolete-storage data; vocabulary blank naming researcher Seiichi Nagihara — "salvage" |
| "Mustang"/"hackamore" etymology | R&W M2 Q23 | Verb-tense blank on "hackamore" from jáquima |
| Great Salt Lake salinity | R&W M2 Q26 | 12C's notes; the ask shifts to Ephydra cinerea vs Achromobacter |
| Tamsin Mather volcano transition | R&W M1 Q21 | Água de Pau vs Methana — verbatim in the bank (R&W M1 Q2), retuned from November's 11A |
| Defoe's The Storm (1704) | R&W M1 Q27 | Verbatim in 12F (R&W M1 Q48); retunes run through the 9J and 8G banks |
| Combo-system skeleton (math) | Math M2 Q20 | y = 4x with 8x − 9y = −56, solve for x + y — retune of 12C's 3x + 8y system |
Note who's missing: 12E carries no brood-care fossils, lighthouse keepers, stony coral, or Taam Ja' Blue Hole — those families live in 12C, 12D, and the bank.
12E Exclusives: Questions Found Nowhere Else
After matching against every other December document, the November set, and the rest of the archive, only three of 12E's 98 questions appear nowhere else:
- The Joseph A. Walker / Negro Ensemble Company notes question — The River Niger (1972) and NEC cofounder Robert Hooks (R&W M1 Q3)
- The Lebrasseur fox-skeleton study — a zooarchaeology team re-examining a fox skeleton found in 1991 (R&W M1 Q18)
- The Pleistocene sewing-technology table — sites by latitude, with technologies and years before present (R&W M2 Q25)
Three exclusives out of 98 makes 12E December's most recycled US form.
Deep Analysis: What 12E Tests, Module by Module
Reading & Writing — Domain Distribution (54 questions)
| College Board domain | Module 1 | Module 2 | Total | Share |
|---|---|---|---|---|
| Information & Ideas (main idea, evidence, data, inference) | 7 | 6 | 13 | ~24% |
| Craft & Structure (vocab, text structure, cross-text) | 4 | 6 | 10 | ~19% |
| Expression of Ideas (transitions, notes/synthesis) | 4 | 5 | 9 | ~17% |
| Standard English Conventions (grammar, punctuation) | 5 | 6 | 11 | ~20% |
| Other / unclassified in auto-index | 7 | 4 | 11 | ~20% |
The classifiable core tracks the published blueprint. Module 1 opens with heavyweight literature (Dickens, then the Arshamian olfaction study); Module 2 bookends itself with data tables — river lengths at Q1, sewing technology at Q25.
Math — The Bank's Greatest Hits, Re-Sequenced
Module 1 (22 questions) is a broad mixed module — two circle items, two right-triangle trigonometry items, linear systems, statistics — anchored by the g(2) radical-collapse (shared with November's 11B and 11G) and the verbatim Ella-evaporation function from 12C's easy Module 2. Module 2 (22 questions) mixes speeds: one-step ratios, the y-intercept of y = 2x² + 7x + 26 (a family running through 12D, 11D, 11E, and the bank), a scatterplot line-of-best-fit read, and the (6x + 5)(x + 2) expansion shared with the 8G bank and 11A. Nothing is exotic; everything is a costume change on a familiar frame.
Tips for Students Using 12E
- Sit 12E as the timed mock; keep 12F open as the answer atlas. Nearly every 12E question appears in the bank, often twice with different letters.
- Read the ask before the notes. 12E's Great Salt Lake item keeps 12C's notes but changes the goal. The bullets are skimmable once you know the goal.
- Combo-systems: solve for the combo, not the variables. In y = 4x with 8x − 9y = −56, substitute first and compute x + y directly.
- Let the radical collapse. g(2) in √(4x − 8)(4x + 8) + 4 is 4 because the root hits zero.
- Grammar blanks reward parallelism. "Hackamore ______ from jáquima" parallels "comes from mesteñas" — match the tense already established.
