Pre-Calculus CBE — Practice Tests & Mock Exams
Texas CBE prep · TEKS §111.42 (NOT AP® Precalculus). Functions, trigonometry, sequences, conic sections, and analytic geometry — the bridge between Algebra 2 and Calculus. This service prepares Texas HS-level Precalculus for CBE credit through UT High School / Texas Tech K-12; it is not designed for the College Board AP® Precalculus exam. AP® is a registered trademark of the College Board, which was not involved with this product.
Practice tests & mock exams
Free practice gives instant feedback on every answer. The full mock mirrors the real exam's length and timing.
How the practice works
Passing-score thresholds vary by district (Texas state code: 80% for §28.023 acceleration, 70% for §74.24 prior-instruction credit). Confirm your specific district's threshold with your school counselor in writing.
Students usually take Algebra 2 before Pre-Calculus. You can still start here anytime — this is a study-order guide, not a requirement.

Pre-Calculus CBE — Frequently asked questions
What topics are on the Pre-Calculus CBE?
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.
How hard is the Pre-Calculus CBE?
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.
How long is the Pre-Calculus CBE?
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.
Is trigonometry on the Pre-Calculus CBE?
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.
Do I need a graphing calculator for the Pre-Calculus CBE?
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.
What math should I master before taking the Pre-Calculus CBE?
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.
What's the passing score for the Pre-Calculus CBE?
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.
I'm not in Texas — does Pre-Calculus prep here still apply?
Yes. Pre-Calculus content — functions and transformations, trigonometry, conic sections, sequences — is the same in every state's Pre-Calculus or Math III course, and prepares for AP Calculus AB/BC equally well. Our questions are TEKS-aligned by origin but the math is universal. Students preparing for AP Pre-Calculus or state-specific Pre-Calc finals find the practice equally valuable.
