PSAT Math Review: What to Practice One Month Before the Test for Parents: September 2026 Edition

A parent-friendly September 2026 PSAT math review plan for the final month before the October PSAT/NMSQT testing window.

If your child is taking the PSAT/NMSQT in October 2026, September is the right time to move from general math review into targeted PSAT math practice. One month is not enough time to relearn every high school math course from scratch, but it is enough time to tighten the highest-value skills, build calculator confidence, and reduce careless errors.

For 2026, College Board lists the PSAT/NMSQT school-day testing window as October 1-30, with a Saturday option on October 17. The digital PSAT math section has 44 questions, split into two 35-minute modules, and students may use an approved calculator for the entire math section.

The Short Answer for Parents

In the final month, the best PSAT math review is a repeating cycle: diagnose, practice one weak domain, review every missed problem, then take a short mixed set. Students should spend the most time on Algebra and Advanced Math because those domains carry the largest share of the math section. Problem-Solving and Data Analysis, Geometry, and Trigonometry still matter, but they are best reviewed through focused mini-sets rather than long formula memorization sessions.

What to Practice First

Priority Skill Area What to Review
1 Linear algebra Solving equations, inequalities, systems, slope, intercepts, and word-problem setup.
2 Advanced Math Quadratics, equivalent expressions, nonlinear functions, exponents, and function notation.
3 Data and percents Ratios, rates, proportions, percent change, tables, scatterplots, and statistics basics.
4 Geometry and trig Area, volume, angle facts, right triangles, Pythagorean theorem, circles, and basic trigonometry.

Week 1: Take a Diagnostic and Fix Algebra Gaps

Start with one official digital practice set in Bluebook or another timed PSAT-style math set. Do not make the first week a “study everything” week. The goal is to identify the student’s three most common error types. Most students fall into one of these groups: they know the math but rush, they struggle with algebra setup, or they cannot choose the correct method when the problem is worded differently.

For algebra review, focus on these tasks:

  • Solve equations with variables on both sides.
  • Write a linear equation from a table, graph, or word problem.
  • Find slope from two points and interpret it as a rate.
  • Solve systems by substitution, elimination, and graphing.
  • Identify when a system has one solution, no solution, or infinitely many solutions.

Week 2: Advanced Math Without Panic

Advanced Math is where many PSAT students lose points because the questions look more abstract. Parents do not need to reteach Algebra 2. Instead, help the student practice recognizing forms. A quadratic in factored form reveals zeros. Vertex form reveals the turning point. An exponential expression reveals a growth or decay factor. Equivalent expressions often require factoring, expanding, or using exponent rules.

Practice example: If f(x) = x^2 – 6x + 5, what are the x-intercepts? Factor: x^2 – 6x + 5 = (x – 1)(x – 5). The x-intercepts are x = 1 and x = 5.

Parent check: Ask your child to explain why the method works. If they can only say “I guessed” or “the calculator showed it,” they need one more written practice problem of the same type.

Week 3: Data, Percents, Geometry, and Calculator Strategy

The digital PSAT includes an embedded Desmos calculator, and students may also use an approved calculator. Calculator access is helpful, but it does not replace setup. Week 3 should mix calculator-aware practice with paper reasoning. Students should know when to graph a system, when to solve by hand, and when a quick estimate can eliminate two answer choices.

  • For percents, always identify the original amount before calculating percent change.
  • For graphs and tables, write what the x-value and y-value represent before calculating.
  • For geometry, write the formula first, then substitute values.
  • For right triangles, check whether the problem asks for a leg, hypotenuse, area, or angle relationship.

Week 4: Timed Mixed Practice and Error Log Review

The last week should feel like test rehearsal, not a crash course. Have the student complete two timed math modules of 35 minutes each. After each module, sort missed questions into four columns: concept gap, setup mistake, arithmetic error, and timing/guessing. This prevents vague review. A student who missed six questions for arithmetic reasons needs a different plan than a student who missed six questions because of quadratics.

A Simple September Schedule

Day Type Time Task
School night 25-35 minutes 10 targeted questions plus review of every missed item.
Weekend day 60-75 minutes One timed module or two smaller mixed sets.
Final three days 20-30 minutes Light mixed review, calculator check, and sleep routine.

Mini Practice Set

  1. Solve: 3(x – 4) = 2x + 9.
  2. A line passes through (2, 5) and (6, 13). What is its slope?
  3. A $72 item is discounted by 15%. What is the sale price?
  4. Factor: x^2 + 7x + 12.
  5. A right triangle has legs 8 and 15. Find the hypotenuse.
  6. The function g(x) = 2x^2 – 3. Find g(4).

Answers

  1. x = 21. Expand: 3x – 12 = 2x + 9, so x = 21.
  2. 2. Slope = (13 – 5) / (6 – 2) = 8 / 4 = 2.
  3. $61.20. Fifteen percent of 72 is 10.80; 72 – 10.80 = 61.20.
  4. (x + 3)(x + 4).
  5. 17, because 8^2 + 15^2 = 64 + 225 = 289 and sqrt(289) = 17.
  6. 29, because 2(4^2) – 3 = 32 – 3.

How ViewMath Fits the Month

Use ViewMath PSAT and algebra resources when the diagnostic shows a pattern: too many missed linear equations, weak function notation, slow quadratic recognition, or inconsistent formula use. The best final-month resource is not the thickest book. It is the one a student will actually use: short explanations, enough practice problems, and detailed answers that make mistakes visible.

Parents can help most by protecting the routine, asking for an error log, and keeping the tone calm. A strong September plan should make the October PSAT feel familiar, not mysterious.
