Every TSIA2 math problem on this platform is built from one of four official College Board content categories. Browse representative examples below — each page shows worked solutions, common student errors, and the underlying skill being measured.
The Texas Higher Education Coordinating Board organizes TSIA2 math into four reasoning strands — twelve diagnostic items each. Our problem bank mirrors that structure exactly.
Ratios, proportions, and percents. Linear equations and expressions in real-world contexts. The arithmetic backbone of college-readiness math.
→Solving linear, quadratic, polynomial, exponential, rational, and radical equations. Evaluating functions. Word problems requiring algebraic modeling.
→Unit conversion within measurement systems. Perimeter, area, surface area, and volume. Transformations and right-triangle trigonometry.
→Classifying data and constructing representations. Computing and interpreting probability. Measures of center and spread.
Students see problems calibrated to their current mastery level within each category. Misses trigger remediation; streaks unlock harder items.
Matches the official TSIA2 format: untimed, computer-adaptive, multiple-choice. Results surface strengths and gaps by category.
Any category — or mix of categories — can be exported to a print-ready worksheet via the Worksheet Generator, branded for your campus.
