Genetics & Molecular Biology

DNA replication, transcription, translation, gene regulation, and heredity. The AI tutor breaks down complex molecular pathways into step-by-step visual explanations.

Virtual Lab Simulations

Practice the 13 AP Bio lab investigations digitally. Run virtual experiments on diffusion, enzyme catalysis, cell division, and more — then answer lab-based FRQs.

Ecology & Evolution

Population dynamics, energy flow, natural selection, and speciation. Adaptive practice ensures you spend more time on the units where you score lowest.

Practice FRQs with AI Grading

Write free-response answers and get instant AI feedback on your reasoning, use of evidence, and scientific vocabulary — the same criteria AP graders evaluate.

Frequently asked questions

Does Koydo cover all 8 AP Biology units?

Yes. Koydo covers all eight units of the AP Biology curriculum: Chemistry of Life, Cell Structure and Function, Cellular Energetics, Cell Communication and Cell Cycle, Heredity, Gene Expression and Regulation, Natural Selection, and Ecology.

How do the virtual lab simulations work?

Koydo's virtual labs let you set variables, run experiments, collect data, and draw conclusions — mirroring the 13 AP Biology lab investigations. After each lab, you answer lab-based questions with AI feedback on your experimental reasoning.

Can Koydo help me prepare for AP Bio alongside other AP exams?

Absolutely. Your Koydo subscription includes prep for every AP exam, the SAT, and the full K-12 curriculum. Many students prep for AP Bio and AP Calculus simultaneously using a single study plan.
