GED® Science: Scientific Reasoning & Practices
About half of the GED® Science test is not about memorizing facts -- it is about thinking like a scientist. This course builds those test-day skills directly: how to design a fair experiment, read tables and graphs, tell correlation from causation, summarize data with averages and probability, handle scientific notation and units, and draw conclusions an examiner will accept. These reasoning skills work hand in hand with the Life, Physical, and Earth & Space Science courses and apply to every passage you will see on the real test.
