GED® Science Practice Test 3: Expert Challenge

The hardest of the early-tier GED® Science practice exams, for students who have cleared Levels 1 and 2. Same test-day format -- 34 questions across Life, Physical, and Earth & Space Science, 90 minutes, scored 100-200 (145 to pass) -- but the items sit at the top of the range: multi-step reasoning, quantitative data and calculations, negative-feedback mechanisms, and critiquing experimental design and conclusions. Every question includes a worked explanation and a pro tip, and many reuse the diagram library.
