Praxis General Science 5436 Study Guide 2026–2027 | 200 Practice Questions

Prepare for the Praxis® General Science (5436) test with a complete study guide organized around the four ETS content categories. Each chapter condenses what the test measures into clear explanations, summary tables, worked examples, key-concept boxes, common-misconception notes, and labeled diagrams, so you can review chemistry, physics, life science, and Earth and space science in one place.

This 163-page digital guide pairs a focused content review with two 100-question practice tests of exam-level questions, so you can practice reading data tables, evaluating investigations, solving problems without a calculator, and choosing how to teach a concept, the way the test asks.

What's Inside

• An overview of the current test: 135 selected-response questions in 2 hours 30 minutes, the four content categories and their weights (15/37/26/22%), scaled scoring, state-set qualifying scores, the on-screen periodic table and constants, fees, and retakes
• Nature and Impact of Science and Engineering: the nature of science, investigation design, units, significant figures and error analysis, laboratory safety, engineering design, environmental issues, energy resources, and science in daily life
• Physical Science: atomic and nuclear structure, matter, energy and thermodynamics, bonding, the periodic table, reactions and stoichiometry, solutions, acids and bases, motion and forces, electricity and magnetism, and waves, sound, and optics
• Life Science: cells and transport, cell division, biochemistry, respiration and photosynthesis, genetics and protein synthesis, evolution, classification, plant structure, animal systems and homeostasis, and ecology
• Earth and Space Science: the Sun–Earth–Moon system, the solar system and Kepler's laws, stars and the universe, plate tectonics, rocks and minerals, Earth's history, the hydrosphere, weather, and climate
• 25 labeled science diagrams, a formula and relationship quick reference, and a final review checklist
• Four-, eight-, and twelve-week study plans, FAQs, test-taking strategies, and recommended resources
• 2 practice tests (200 questions, 4 answer choices each) weighted like the real test's four categories, with data tables, investigations, and classroom scenarios, plus a separate answer key explaining every answer
