Lessons with Apo need a plan; practice is free. Both run in your computer’s browser.

Aporo runs in a computer browser. Send yourself the link and open it there.

  1. Bring the question you got wrong.

    Type it, paste it or snap a photo. No question handy? Start a random SAT problem or pick a topic.

  2. Show your working.

    Talk it through, type it, or write it on the whiteboard. Apo reads every step, not just your final answer.

  3. Apo finds the step that slipped.

    Instead of handing you the answer, he points at that step and asks you one question about it.

  4. You make the fix.

    You correct it yourself, and Apo checks the rest of your steps. If you’re still stuck, Explain visually draws the idea out.

    Try it on your own question

The graph of y = x² − 6x + c meets the line y = 2 at exactly one point. What is c?

Your working

x² − 6x + c = 0

36 − 4c = 0

c = 9

Your fix

x² − 6x + c = 2

36 − 4(c−2) = 0

c = 11

Apo

How would you start?

Where did the line y = 2 go?

Yes! With y = 2, c = 11.

Illustrative lesson on a hard SAT Math question.

Every wrong answer has a fork.

An answer key shows the right path. It never shows where yours left it, so the same slip comes back on test day. Apo finds the fork.

The graph of y = x² − 6x + c meets y = 2 at exactly one point. What is c?

Pick an answer to trace its path.

SAT tutor means a scheduled human lesson with a shared writing surface; tools vary by provider.
