TExES Mathematics 4-8 Practice Center
Take a full form, then read the explanation under every question you missed. Note that a quarter of this exam is not computation: Domains V and VI are about mathematical reasoning and about how students learn mathematics, and they need a different kind of study from the content domains.

TExES Mathematics 4-8 at a glance
This is the Texas middle grades mathematics certification exam. The content reaches from place value through functions and coordinate geometry, which is what candidates expect. What they often do not expect is that a quarter of the exam is not content at all: Domain V is mathematical processes and reasoning, and Domain VI is about how students learn mathematics and how you would respond to their work.

Texas publishes weights by domain: Number Concepts 16 percent, Patterns and Algebra 21 percent, Geometry and Measurement 21 percent, Probability and Statistics 16 percent, Mathematical Processes and Perspectives 10 percent, and Mathematical Learning, Instruction, and Assessment 16 percent. That last pair is 26 percent between them, so more than a quarter of this exam is about reasoning and teaching rather than about computing.

Before test day
The mistake to avoid is preparing for this as a pure content exam. More than a quarter of it asks about reasoning and about students, and those questions reward a different habit: on any item that shows you student work, name the specific error before you read the choices, because the wrong answers are written to be attractive to someone who has not. On the content side, unit conversion in two and three dimensions quietly costs more points than any single topic.
