An example correction, in biology

BiologyIllustrative example
Your answer

Why doesn’t an antibiotic help with the flu?

Because the flu virus has become resistant to antibiotics.

Resistance is not the reason.

Antibiotics attack parts that only bacteria have, such as the cell wall and their ribosomes. The flu is caused by a virus, which has neither, so the drug never had anything to act on.

Antibiotics act on bacteria, not on viruses.

Read it in the source

Antibacterial drugs act on structures specific to bacteria, such as the cell wall and the 70S ribosome. OpenStax, Microbiology, §14.3.

A correction you can inspect. See the second attempt.

The same works for any subject you study: history, law, economics, languages, programming, calculus.

Watch the study workflow unfold.

Start by creating a course, here Calculus I. Choose a chapter to see how course materials, planning and review connect.

  1. Create the courseAdd your exam dates and upload PDFs, problem sets and past exams. Material, conversations and tasks stay together in the course.
  2. Ask about your materialThe tutor answers from your files. Click a citation and the PDF opens on the page the answer came from.
  3. Plan up to each examSay how much time you have a day. Inspect proposed sessions before adding them to your week, and request changes when your routine changes.
  4. Do the day's sessionThe tutor teaches the task's point, you try the problem, ask for more practice if you want, and finish.
  5. Get a study guide and a mock examThe guide is written from your material. Request a mock exam in your exam's format, one question at a time, against the clock.
  6. Review with flashcardsCards from what you studied, with spaced repetition: NodeStudy schedules when each one comes back.

Screen recording of a demo account. Waits are shortened and the tutor's writing is sped up. The tutor's answers in these clips are example text.

From an attempt to the next practice.

  1. Try a question

    Bring your material and show your reasoning. Ask for an explanation or choose how much help to receive.

  2. Understand the correction

    Inspect the step that needs attention, with sources and check records where available.

  3. Apply it again

    Work through a related question, then return to the idea with the error notebook and review.

Sources, limits and your data.

Which subjects does it work for?

Any subject you have material for. Upload class notes, slides, a textbook chapter or past exams, and the tutor answers from them: biology, history, law, economics, languages, programming and more. For calculations, such as calculus, statistics or physics, it can also check the result with code. The method page explains what a check covers.

Can the tutor make mistakes?

Yes. Sources and tools help you inspect an answer, but do not certify every sentence. The method page explains the scope of checks.

What informs the method?

Roediger and Karpicke (2006) studied retrieval practice and delayed retention. FSRS estimates review intervals.
