upgraded study guides for ap biology

october 16, 2025

Every AP Biology study guide was checked against the official CED and strengthened where it mattered.

These guides were already written by teachers using the Course and Exam Description. Now they're tighter. Concepts that were mentioned briefly are explained more fully. Examples match what the CED actually emphasizes. Small errors and typos cleaned up.

This wasn't a rewrite โ€” it was a targeted upgrade. The stuff that worked stayed. The stuff that could be clearer or more accurate got fixed.
