Pre-Calculus CBE — Practice Tests & Mock Exams

The Pre-Calculus CBE covers TEKS §111.42: mathematical process standards, functions and their properties (domain, range, composition, inverse, transformations), polynomial and rational functions, exponential and logarithmic functions, trigonometric functions (unit circle, identities, equations), sequences and series, and conic sections, parametric/polar equations, and vectors. Semester A is non-trig (functions, polynomial/rational, exp/log); Semester B is trig-heavy plus sequences, conics, and vectors.

It's the most demanding math CBE Texas offers at the high-school level — designed as the bridge between Algebra 2 and Calculus. Expect a roughly even split between conceptual reasoning (identifying function behavior, asymptotes, symmetry), algebraic manipulation (solving log/exp/trig equations), and graphical interpretation (reading transformations, sinusoidal models, conics). Students who score 85%+ on our mocks typically pass on the first attempt.

About 3 hours with 50 multiple-choice questions per semester. Our mock exams match the format exactly — same time limit, same question count, same balance of computational and conceptual items — so your pacing practice transfers directly to test day.

Yes — about 40% of Semester B is trigonometry. The unit circle, special-angle values (sin/cos/tan of π/6, π/4, π/3), Pythagorean and double-angle identities, and solving trig equations are all heavily tested. Memorize the unit circle and the six fundamental identities; everything else builds from those.

A scientific or graphing calculator is permitted and strongly recommended. You'll need it for natural log evaluations, trig values at non-special angles, polynomial root-finding, and exponential growth/decay problems. Our practice questions assume calculator access so your prep rehearses with the same tool.

Strong Algebra 2 fluency is essential: factoring polynomials, solving rational equations, manipulating exponents and logarithms, and graphing functions. If you struggle with Algebra 2 mock exams, build that foundation first — Pre-Calc moves fast and assumes you already own those skills.

70% — the same as all UT High School CBE exams. We recommend targeting 85%+ on full-length mocks because the trig identity and conic-section questions can spike in difficulty depending on which TEKS standards your specific exam draws from.
