CSET Multiple Subjects — Subtest II Mathematics
Expanded 2026–2027 Practice & Study Guide
Independent preparation resource — not an actual or leaked examination. This guide uses the public Stuvia listing only as a
topical/format reference and contains newly authored practice questions and explanations.
Source snapshot. The supplied Stuvia listing is 17 pages, uploaded March 20, 2026, written for the 2025/2026 academic year, and
describes topics including number sense, algebra, geometry, measurement, and data analysis. Its preview contains Q&A; with
rationales. ■cite■turn0view0■
Official alignment. California's Multiple Subjects examination has three subtests; Subtest II covers Science and Mathematics. The
official CTC content specifications organize Multiple Subjects Mathematics into Number Sense, Algebra and Functions, Measurement
and Geometry, and Statistics, Data Analysis, and Probability. ■cite■turn1search0■turn1search25■
Important distinction: this is CSET Multiple Subjects Subtest II Mathematics, not CSET Mathematics Subtest II (the latter is the
Foundational-Level Mathematics exam's Geometry/Probability-and-Statistics subtest).

, 1. Exam Blueprint & Strategy
For the Multiple Subjects exam, each subtest uses multiple-choice and constructed-response items. The Commission lists 39
multiple-choice questions and 3 constructed-response questions for each Multiple Subjects subtest, with a passing score of 220;
Subtests I and II are allocated three hours each. ■cite■turn1search5■
For Mathematics specifically, the current content specifications emphasize number sense, algebra/functions, measurement/geometry,
and statistics/data/probability. Use this guide to practice both computation and explaining why a method works.
Fast strategy: (1) estimate before calculating, (2) label units, (3) translate words into a representation, (4) check whether the answer is
reasonable, and (5) for constructed response, state the rule, show the work, and interpret the result.
2. Number Sense & Operations
Question. A student says 0.4 is greater than 0.35 because 4 is greater than 3. What is the best correction?
Choices: A. Agree because 4 > 3. B. Rewrite 0.4 as 0.40 and compare 0.40 with 0.35. C. Convert both to whole numbers. D. Multiply
both by 0.1.
Answer: B
Why: Decimal place value is positional. Writing 0.4 as 0.40 makes the tenths/hundredths comparison explicit: 40 hundredths > 35 hundredths.
Question. Which is the greatest common factor of 36 and 48?
Choices: A. 6 B. 8 C. 12 D. 18
Answer: C
Why: Prime factorization gives 36=2²·3² and 48=2■·3, so the common product is 2²·3=12.
Question. Which statement about 1 is correct?
Choices: A. 1 is prime. B. 1 is composite. C. 1 is both prime and composite. D. 1 is neither prime nor composite.
Answer: D
Why: A prime has exactly two positive factors; a composite has more than two. One has exactly one positive factor.
Question. What is 3/4 ÷ 1/2?
Choices: A. 3/8 B. 2/3 C. 3/2 D. 1/2
Answer: C
Why: Divide by a fraction by multiplying by its reciprocal: 3/4×2/1=6/4=3/2.
Question. Which is equivalent to 2.5 × 10³?
Choices: A. 250 B. 2,500 C. 25,000 D. 0.0025
Answer: B
Why: 10³=1,000, so 2.5×1,000=2,500.
Question. A recipe uses 3 cups for 8 servings. At the same rate, how many cups are needed for 20 servings?
Choices: A. 6 B. 7.5 C. 8 D. 10
Answer: B
Why: The unit rate is 3/8 cup per serving; 20×3/8=60/8=7.5 cups.
Question. Which estimate is most reasonable for 49.8×2.1?
Choices: A. 10 B. 50 C. 100 D. 500
Answer: C
Why: 49.8≈50 and 2.1≈2, giving about 100.
