Amoeba Sisters Biology Learning Playlist
Use for approachable biology previews, then force mastery through data and explanation checks.
An AP Biology path centered on chemistry of life, cells, energetics, communication, heredity, gene expression, natural selection, ecology, and data-driven biological argument.
An AP Biology path centered on chemistry of life, cells, energetics, communication, heredity, gene expression, natural selection, ecology, and data-driven biological argument.
This track is organized as a mastery loop: source study, sequenced checks, Khan report evidence, then tutor handoff only when the data shows a real stuck point.
Use linked OER and companion sources before attempting checks.
Move through numbered PeerTutor problems without skipping failed gates.
Enter Khan report evidence and let the adaptive plan rank repair units.
Bring exact misses, notes, and one sharp question to a tutor.
The bank is intentionally mixed across facets and difficulty so high scores cannot come from one narrow question style.
Use these linked courses for video instruction and mastery practice, then return here for PeerTutor original checks and tutor help on the exact unit that got stuck.
External video content is linked or embedded through provider-hosted players, not copied. PeerTutor practice is original and cites each source path separately.
Watch the strongest public video path inside PeerTutor, then use the unit checks below to prove the student can actually do the work.
Use for approachable biology previews, then force mastery through data and explanation checks.
Use for concise AP Biology topic review alongside the unit data checks.
Concise science explainers for physics, chemistry, biology, astronomy, and earth science.
Khan Academy progress has to be entered from the student or tutor report. Khan does not provide a supported public progress API, so this mirror stores unit status locally and uses it to target PeerTutor checks.
Khan Academy does not provide a supported public progress API or external API keys. PeerTutor stores student-provided report evidence and maps it to original practice instead.
0 repair units and 5 practice units need attention before extension.
