1. Level 2: What's Harder
GED® Science: Full-Length Practice Exam (Level 2 - Advanced) · preview lesson
This is the advanced GED® Science practice exam. The format matches the real test and Level 1:
- 34 questions in 90 minutes, across Life Science, Physical Science, and Earth & Space Science.
- Scored 100-200, with 145 to pass. No penalty for wrong answers.
What's harder here than Level 1: the questions move past single facts to relationships and mechanisms -- how photosynthesis and respiration connect, how natural selection works, how forces produce acceleration -- and they lean harder on reading graphs and data and on experimental reasoning.
Two variables rise together on a graph. Does that prove one caused the other? Answer yes or no.
Correlation is not causation -- a third factor could explain both.
