The GED measures reading and reasoning more than recall. We teach the reasoning skills first — then layer in just enough content to cover what the test actually asks.
Most adults haven't seen biology since high school. The first module is a deliberate refresh on scientific reasoning — not memorizing the periodic table. We teach the patterns the GED actually tests.
Reading scientific data is a big part of the GED Science test — and it's a skill, not a talent. Lessons on data presentations, conclusions and evidence take it one step at a time.
Doesn't matter. The GED Science test isn't memorization-heavy. It's about reading and reasoning. Our chemistry module covers the basics the GED touches in six short lessons.
