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.
The Texas STAAR 생물학 EOC tests the same TEKS standard our practice covers. The same purchase serves both CBE and STAAR EOC preparation. How the overlap works →

생물학 CBE — Frequently asked questions
What topics are on the Biology CBE?
The Biology CBE covers cell structure and function, mechanisms of genetics, biological evolution and classification, biological processes and systems, and interdependence within environmental systems. Each TEKS reporting category is sampled across Semester A and B mock exams.
How hard is the Biology CBE?
Expect a mix of factual recall (cell organelles, DNA replication steps, classification levels) and applied reasoning (interpreting graphs, predicting genetic outcomes, analyzing ecosystems). Lab-based experimental design questions are common. Students hitting 80%+ on our mocks typically pass first attempt.
How long is the Biology CBE?
The exam runs about 3 hours with roughly 55–60 questions. Our mock exams match this length and include the same diagram-heavy and graph-interpretation style so your pacing practice is accurate.
Do I need to memorize all the cell organelles?
Yes — and their functions. The CBE tests on cell structure recurrently. Our practice questions emphasize this: organelle identification from electron micrographs, function matching, and contrasting prokaryotic vs. eukaryotic features.
Is there a lab component to the Biology CBE?
No physical lab, but expect questions about experimental design — controls, variables, hypothesis testing, and interpreting lab data. About 15–20% of questions reward strong scientific method understanding.
What's the passing score for the Biology CBE?
70%. Aim for 85%+ on practice mocks because the genetics and ecology questions can spike in difficulty depending on which TEKS standards your specific exam draws from.
I'm not in Texas — does Biology prep here still apply?
Yes. Biology content — cell structure, genetics, evolution, body systems, ecology — is taught in every state's high school Biology course (often called Living Environment in NY). Our questions are TEKS-aligned by origin but the biology is universal. NY Regents Living Environment, CA NGSS-aligned biology, and FL B.E.S.T. Biology students often use the platform for review.
