Test Structure and Administration Overview

• The full assessment consists of 98 questions divided into four modules: two for Reading & Writing and two for Math.

• The total duration of the exam is 134 minutes.

• Materials required for the test include a pencil, an approved calculator, and scratch paper.

• The Reading & Writing section contains 54 questions total, split into two 27-question modules. Each module has a suggested time limit of 32 minutes.

• The Math section contains 44 questions total, split into two 22-question modules. Each module has a suggested time limit of 35 minutes.

• The exam utilizes adaptive routing. Every student begins with Module 1, which includes a broad mix of easy, medium, and hard questions. Performance on Module 1 determines the difficulty level of the second module.

• In this specific practice exam, Module 2 is fixed as the higher-difficulty route, which is associated with a higher attainable score range than the lower-difficulty route on the official digital exam.

Reading & Writing Content and Passage Analysis

Arts and Literature

• An art club completed a large cafeteria mural by adding the final details for a spring showcase at the end of May.

• Maren, the protagonist of Ingrid Halvorsen's 1908 novel The Weaver's Loom, is an aging Norwegian weaver who takes pride in her 40-year craft but fears that younger villagers ignore her loom and no longer value the tradition.

• The muralist Judith Baca created a half-mile-long project along a Los Angeles flood-control channel. Her central goal was to involve hundreds of local youth to reflect community voices and depict historical scenes often omitted from textbooks.

• The Ghanaian sculptor El Anatsui uses discarded materials, such as bottle caps and aluminum fragments, to create enormous shimmering wall hangings that resemble woven cloth.

• Kente cloth, produced by Akan weavers in Ghana, is characterized by intricate geometric patterns and vivid colors.

• Author Mariam Okafor achieves verisimilitude in her historical novels by researching household inventories, candle prices, and dockworker slang to make her characters feel authentic.

• Bordalo II, a Portuguese artist, creates large animal sculptures from urban trash, such as a coastal bird made from broken plastic buckets, fishing nets, and pipes.

• Buchi Emecheta wrote In the Ditch (1972) and Second-Class Citizen (1974), both of which explore the challenges of raising five children in London.

• In The Portrait of a Lady (1881) by Henry James, the narrative uses focalization—restricting the story to the consciousness of Isabel Archer as she explores an English country house.

Science and Natural History

• Beaver dams built of branches, mud, and stones slow stream flow and create wetlands. Removing beavers increases the risk of downstream flooding because heavy rainfall is no longer stored and released gradually.

• Solid-state batteries replace liquid components with solid material to increase energy density. Experimental cells grew from roughly $300\,Wh/kg$ in 2015 to about $400\,Wh/kg$ by 2023, though production costs remain a barrier to widespread vehicle use.

• Honeybees (studied by Shihao Dong) use a 'waggle dance' to communicate food locations. While direction signaling improves with individual practice, social learning from experienced dancers is required to calibrate distance signals accurately.

• Nizar Ibrahim's 2020 discovery of a tall, paddle-shaped tail in Morocco suggests that the dinosaur Spinosaurus was a capable swimmer and aquatic hunter, contradicting the previous view of it as a land animal.

• Trinidadian guppies (studied by Ana Restrepo) form tighter schools in high-predation areas to reduce individual risk. Conversely, killifish loosen their groups in the same environments because they are ambush predators that rely on dispersal and concealment.

• Ana Villanueva found that many brightly colored Central American frogs are not toxic; they mimic the coloring of poisonous species to avoid predators, challenging the idea that vivid colors always indicate toxicity.

• Urban male songbirds sing longer, more elaborate songs compared to rural males, a behavior attributed by Priya Raman to the need to be heard over city traffic and machinery.

• Cape ground squirrels in the Kalahari use their bushy tails as portable parasols, reducing the environmental temperature by more than $5^{\circ}C$ to allow longer foraging periods in the sun.

• Mycorrhizal networks allow carbon to move between forest trees via fungi, though this does not necessarily prove that older trees deliberately share resources to improve seedling survival.

Social Science and Architecture

• Archaeologists discovered a Bronze Age village built on wooden stilts above a European lakeshore. Preserved tools and grain stores suggest the community was permanent rather than a temporary seasonal camp.

• Modern libraries have found that moving new arrival shelves to the main entrance increases checkouts by exposing patrons to titles they did not originally intend to borrow.

• Aztec cacao beans were used as money, with a single rabbit costing approximately 30 beans. Counterfeit beans, made of hollow shells filled with clay or wax, indicate the high value of the currency.

• In Singapore, rooftop gardens of soil and greenery reduce heat in classrooms and lower air conditioning costs by blocking direct sunlight.

• The ancient city of Petra in Jordan features tombs and temples carved into rose-colored cliffs by the Nabataean people.

• Alfred Wegener proposed the theory of continental drift in 1912, citing matching fossils and rock formations, though his theory was initially rejected because he could not explain the driving force behind the movement.

• Geodesic domes, popularized by Buckminster Fuller, use a network of triangles to distribute loads evenly. Because triangles resist deformation, these domes can support heavy weights with minimal material.

Mathematics: Formulas, Procedures, and Data

Algebra and Functions

• A meal costing $d$ dollars with an $8\%$ sales tax has a total cost of $1.08d$. For a meal costing $45.00\,dollars$, the total is $45 \times 1.08 = 48.60\,dollars$.

• For the line $y = 2x + 8$, lowering the line by 12 units results in the new equation $y = 2x - 4$. The $x$-intercept occurs where $0 = 2x - 4$, resulting in $x = 2$.

• Priya's reading-rewards balance at the Halworth Library is modeled by the linear equation $t = 6w + 50$, where $50$ is the initial balance in dollars, $6$ is the amount added weekly, and $w$ is the number of weeks.

• The equation $\lvert x - 5 \rvert + 2 = 11$ simplifies to $\lvert x - 5 \rvert = 9$. The solutions are $x = 14$ and $x = -4$. The value below zero is $-4$.

• The expression $x^2 + 12x + 40$ can be rewritten in the form $(x + a)^2 + b$ by completing the square: $(x + 6)^2 + 4$. The sum $a + b$ is $6 + 4 = 10$.

• The system of equations $y = x + 2$ and $y = 4x - 2$ is solved by setting the equations equal: $x + 2 = 4x - 2$, which yields $3x = 4$ and $x = \frac{4}{3}$. Alternatively, the intersection of curves $y = x + 2$ and $y = 4x - 2$ can involve points like $(3, 5)$, where the larger $x$-coordinate is $5$.

• The profit model for the Mirelda cart given the pastry price $x$ and profit $y$ is $y = 2x^2 - 10x + 12$.

• The equation $6x^2 - 7x - 20 = 0$ has roots that can be found via the quadratic formula. The root greater than zero is $2.5$.

Geometry and Trigonometry

• In a right triangle with acute angles $(4x + 13)^{\circ}$ and $(2x + 23)^{\circ}$, the sum of these angles must be $90^{\circ}$. Solving for $x$:     $4x + 13 + 2x + 23 = 90$     $6x + 36 = 90$     $6x = 54$     $x = 9$     The smaller acute angle is $(2(9) + 23) = 41^{\circ}$.

• A circle with center $(3, -6)$ and radius $5$ has the equation $(x - 3)^2 + (y + 6)^2 = 25$. Expanding this gives $x^2 - 6x + 9 + y^2 + 12y + 36 = 25$, or $x^2 + y^2 - 6x + 12y + 20 = 0$. The value of the constant $c$ is $20$.

• In a right triangle $FGH$ where the right angle is at $G$, if $FG = 35$ and $GH = 12$, the hypotenuse $FH = \sqrt{35^2 + 12^2} = \sqrt{1225 + 144} = 37$. Then $\sin(F) = \frac{\text{opposite}}{\text{hypotenuse}} = \frac{12}{37}$.

• A storage box measuring $9\,ft$ long, $4\,ft$ wide, and $7\,ft$ tall has a volume of $9 \times 4 \times 7 = 252\,ft^3$.

• Similar rectangles $G$ and $H$ have areas of $50\,cm^2$ and $450\,cm^2$, respectively. The area ratio is $1:9$, meaning the linear scale factor is $1:3$. If the perimeter of $G$ is $30\,cm$, the perimeter of $H$ is $30 \times 3 = 90\,cm$.

Data Analysis and Statistics

• Brimmer trailhead hikers: A typical walk of $7.5\,miles$ with a margin of error of $0.6\,miles$ means the typical walk is reasonably between $6.9$ and $8.1\,miles$.

• Bacteria growth is modeled by $n(t) = 300(2)^{t/9}$. To reach $1,200$ bacteria, we solve $1200 = 300(2)^{t/9}$, which gives $4 = 2^{t/9}$. Since $4 = 2^2$, then $2 = \frac{t}{9}$, so $t = 18\,hours$.

• Talbridge teenager screen time survey: Team Okafor uses random sampling from city records, which supports a valid conclusion. Team Renquist uses convenience sampling at a gaming arcade, which is biased.
