GED® Science: Full-Length Practice Exam (Level 4 - Mastery)
The fourth and second-hardest full-length GED® Science practice exam, for students aiming at a top score after clearing Levels 1-3. Same test-day format -- 34 questions across Life, Physical, and Earth & Space Science, 90 minutes, scored 100-200 (145 to pass) -- but every item is a hard, multi-layered problem: quantitative analysis, energy conservation and electric circuits, protein synthesis and inheritance ratios, evolution mechanisms, feedback systems, and critiquing experimental design and data. Every question includes a worked explanation and a pro tip.
