1.3 How to Study for AAF

Accuracy Beats Speed on an Untimed CAT

AAF is generally untimed and computer-adaptive. That combination should change how you study. Speed drills that help on a 60-minute SAT Math module can hurt here. A missed early item can drop subsequent difficulty, so the engine spends your remaining items confirming a lower band instead of letting you show function transformations or unit-circle values. Slow down on item 1. Recopy the equation. Check the domain. Then submit.

You still should not stall for ten minutes on arithmetic you do not know. Untimed is not infinite. Testing centers have building hours. The winning habit is deliberate accuracy, not a race and not a freeze.

Skills That Pay Off Across Many Items

Drill these until they are automatic. They show up across Table 10 rows, not only in a single chapter.

• Function notation. f(a) means evaluate at a, not multiply f by a. Composition (f ∘ g)(x) = f(g(x)) is not f(x) · g(x).
• Extraneous roots. After you square a radical equation or clear a rational equation, substitute back. Reject values that make a denominator zero or a principal square root negative.
• Graph features. Slope and intercepts for lines; vertex, axis of symmetry, and intercepts for quadratics; holes and asymptotes for rationals; transformations (shifts, reflections, stretches) for the families you graph.
• Exponent and log rules. Product, quotient, and power rules; change of base as a last resort; the inverse relationship b^{log_b x} = x (x > 0).
• Right-triangle trigonometry. sine = opposite/hypotenuse, cosine = adjacent/hypotenuse, tangent = opposite/adjacent; 30°-60°-90° and 45°-45°-90° side ratios.

Worked notation check: if f(x) = 2x − 5 and g(x) = x^2, then (f ∘ g)(3) = f(9) = 13, while (g ∘ f)(3) = g(1) = 1. Students who treat composition as commutative will miss a functions item even if they can graph both functions.

Worked extraneous-root check: 1/(x − 2) = x / (x − 2). Multiply both sides by x − 2 (noting x ≠ 2) to get 1 = x, which does not make the denominator zero, so x = 1 is valid. Contrast with 1/(x − 2) = 2/(x − 2), which collapses to 1 = 2 after multiplying, a contradiction, with x = 2 already excluded. Canceling first without stating exclusions is how otherwise strong students throw away a rational item.

Worked graph-feature check: y = (x − 3)^2 − 8 has vertex (3, −8), axis x = 3, and y-intercept (0, 1). A shift of y = x^2 right 3 and down 8 is the transformation story. If the stem asks for the minimum value, the answer is −8, not the x-coordinate 3.

Official Samples Plus FREE Practice

Use two practice streams:

1. College Board’s AAF sample-questions PDF (linked from the student prepare pages). It is short, official, and includes geometry even when the nine-category student list does not.
2. OpenExamPrep FREE 2026 practice at /practice/accuplacer-advanced-algebra.

Do not copy official stems into a notebook as if memorizing 20 samples were the exam. The CAT will not recycle those 20 items as your test. Use samples to learn item style, then use a larger FREE bank to learn your error patterns.

Hours: A Site Study Estimate, Not a College Board Requirement

OpenExamPrep’s exam-meta planning range for AAF is 20–45 hours. That is a site study estimate, not a College Board official requirement. College Board does not publish a mandatory hour count. Treat 20 hours as a compressed plan for a student who already factors cleanly and only needs functions, rationals, logs, geometry, and trig. Treat 45 hours as a fuller rebuild across all 11 Table 10 domains, still assuming Arithmetic and QAS are not the main problem. If they are, add QAS/Arithmetic time on top of this range.

Calculator Practice Habit

The on-screen calculator appears only on some items. Practice without a handheld. If you currently reach for a TI-84 to compute 3^4, to evaluate 2(−5) + 7, or to check a 30°-60°-90° ratio, you are practicing a tool you may not have. Save mental energy for the items that actually display the top-right icon.

Mapping Study to the 11 Table 10 Domains

Every study week should name the Table 10 row it is feeding:

1. Linear equations
2. Linear applications and graphs
3. Factoring
4. Quadratics
5. Functions
6. Radical and rational equations
7. Polynomial equations
8. Exponential and logarithmic equations
9. Geometry concepts for Algebra 1
10. Geometry concepts for Algebra 2
11. Trigonometry

The diagram below is the path this guide uses: diagnose, repair foundations if needed, then walk the 11 domains, then retest.

A 2-Week Plan (About 20 Hours)

Use this only if linear solving and fraction arithmetic are already stable. Ten study days at about two hours each, plus a lighter review weekend, lands near the 20-hour end of the site estimate.

On day 2, a concrete linear-graph target: write the line through (2, 5) perpendicular to y = (1/2)x − 3. Perpendicular slope is −2, so y − 5 = −2(x − 2), which is y = −2x + 9. If you cannot produce that without a calculator, spend the extra hour here rather than jumping to logs.

On day 7, a concrete rational target: solve (x + 3)/(x − 1) = 2. Then x + 3 = 2(x − 1), x + 3 = 2x − 2, 5 = x, and x = 5 is allowed because it is not 1. If the right side had produced x = 1, you would discard it.

A 6-Week Plan (About 40–45 Hours)

Use this if you need the full site estimate. Plan three sessions per week of 2–2.5 hours, plus a weekly mixed set. That is roughly 40–45 hours without pretending College Board assigned the number.

Week 3 checkpoint item: f(x) = |x − 4| − 1. Domain is all real x; range is y ≥ −1; the V vertex is (4, −1). If you call the range y ≥ 0 because absolute value is never negative, you missed the vertical shift.

Week 5 checkpoint item: 3^{x+1} = 81. Write 81 as 3^4, so x + 1 = 4 and x = 3. Then log_3 81 = 4 as the inverse statement. If 3^{x+1} = 40, the exact form is x = log_3 40 − 1, which is high-band work you should at least recognize.

Week 6 checkpoint item: a 30°-60°-90° triangle with short leg 5 has long leg 5√3 and hypotenuse 10. sin 60° = √3/2. On the unit circle, the same angle has coordinates (1/2, √3/2). Connecting right-triangle trig to the unit circle is the 276–300 top-band move; do not leave it for the night before the test.

Weekly Mixed Set Rules

• Take mixed practice open-notes the first time, then closed-notes.
• Tag every miss with a Table 10 row, not with I am bad at math.
• Re-work the miss the next day without looking at the explanation.
• Stop when accuracy on a 15–20 item mixed set is stable, not when you have exhausted a timer. The real test is untimed.

What Not to Do

• Cram trigonometry for four days while skipping factoring. The CAT can ask a 237–249 factoring item before it ever shows sin 30°.
• Study with a handheld calculator on every homework problem.
• Treat 20–45 hours as a College Board rule you must report to a registrar.
• Ignore What’s on the Tests and also ignore Table 10; use both, and when they disagree on geometry, keep geometry.
• Start AAF content while Arithmetic still fails. Use QAS and Arithmetic first.
