GED® Science Practice Test: Mixed Science Review
A capstone GED® Science practice test that mixes every strand into one comprehensive review: Life Science (cells, energy, genetics, evolution, ecosystems, the human body), Physical Science (matter, atoms, reactions, energy, forces, waves), Earth & Space Science (the rock and water cycles, plate tectonics, weather, the solar system), and the scientific-reasoning skills woven through the whole exam. Free multiple-choice questions with full explanations and pro tips, plus quick recaps of each strand, so you can review all of GED® Science in one place before test day.
