The test is five hours. Your prep should not be.
You have a life. A classroom to run. A future to build. The TExES Life Science 7-12 (238) exam spans six domains, from cell biology to environmental systems. This guide distills everything into a single, focused resource.

Engineered for the TExES 238 blueprint
Every domain gets a dedicated chapter, covering exactly what the exam tests. No tangents. Just the science you need, explained clearly. And with 10 full-length practice tests (100 questions each), you get more realistic practice than most other guides offer.

What you will master inside
• Scientific inquiry: experimental design, data analysis and the nature of science.
• Cell biology: structure, function and processes from transport to mitosis.
• Genetics and evolution: heredity, population genetics and speciation.
• Diversity of life: classification, anatomy and physiology across kingdoms.
• Ecology and environment: ecosystems, cycles and human impact.
