See how Kuest teaches it

It asks before it tells, so you do the thinking and it sticks.

You: Two parents are both Aa. What fraction of their offspring show the recessive trait?
Kuest: Set up a Punnett square. Each parent passes on either A or a. What four combinations do you get?
You: AA, Aa, Aa and aa. The recessive ones are Aa, Aa and aa, so 3/4.
Kuest: The square is perfect. Now check Aa: it carries the recessive allele, but which trait does it actually show when a dominant A is present?
You: The dominant one. So only aa shows the recessive trait. That's 1/4.
Kuest: Exactly, 1/4. The other 3/4 show the dominant trait, and 2/4 of all offspring are carriers.

A recessive trait only shows with two recessive alleles; Aa individuals are carriers.

The method

How to study Biology with Kuest

Biology is a web of ideas more than a list of facts: a term sticks once you can say what it does and why it matters. Explain processes in your own words, then quiz yourself over several days instead of rereading the chapter the night before.

  1. Ask how the process worksTutor chat

    Start with the idea behind the unit, like why cells divide or how genes become proteins, and answer Kuest's questions as you go.

  2. Watch it on the boardTeaching board

    Kuest draws the cell, the stages of mitosis or a food web step by step, so you can see each part before you label it yourself.

  3. Snap diagrams and worksheetsSnap a photo

    Photograph a textbook figure, a pedigree or a Punnett square question and work through it one step at a time.

  4. Review terms with spaced flashcardsFlashcards

    Turn organelles, vocabulary and processes into flashcards that come back just as you start to forget them.

  5. Quiz yourself on each unitQuizzes

    Answer multiple-choice and short written questions, including data and experiment questions like the ones on AP Biology.

  6. Take a timed mock examMock exams

    Before a unit test or the AP exam, sit a full practice test under time and review every miss with Kuest.
