Free GED Section 3 Science: Section Three Science Exam Questions and Answers
The GED was restructured in 2014 and this section belongs to the earlier five-test series. Science remains one of the four current subjects, now a 90-minute computer-delivered paper scored 100 to 200 with 145 to pass. Its content splits across life science, physical science, and earth and space science, and it leans heavily on reading experiments, interpreting data presentations and reasoning from evidence rather than on recalling facts. That emphasis has not changed since this earlier series, so the practice here still builds the right habits even though the timing and scoring have moved.
The first 10 questions on this page are free to read, answers included — no account and no card. A plan opens the rest of the bank, the full timed practice test and your weak-topic reporting.
