The 24-Hour Gap Map. Free, for AP Chemistry, Biology, Physics and Calculus.

One page that shows exactly where the points went.

Your kid does a 45-minute session with a live AP tutor. Within 24 hours, you get one page about the last test: where the points went, the score it could have been, and a dated plan for the next test.

About two minutes. Then we message you on WhatsApp with two times for the session.

We never sell or share your information. We use it only to book the session and send the page.

  • Free. No card. No enrollment.
  • No test at home? One line about what happened is enough.
  • You keep the page either way.

What happens, and when

  1. Today

    You send the form.

    A photo of the last graded test helps, if you have it. If not, one line about what happened is enough to start.

  2. Within 30 minutes

    We message you two times.

    On WhatsApp, during 1–⁠10pm ET, Monday to Saturday. Outside those hours, by 2pm ET the next working day. No WhatsApp? The two times come by email.

  3. The session

    45 minutes, your kid and a live AP tutor.

    No parents, no pitch. A short timed set from the unit just tested. Your kid holds the pen the whole time, and the first thing they hear is what they already do right.

  4. Later that day

    A short call, just with you.

    Booked with the session. We walk you through what we found. And, if you want to hear it, what we'd do about it and the price.

  5. Within 24 hours

    The page, and the marked test.

    Every point explained. You keep it either way.

What's on the page

One page about one test. Choose a line to see it on the sample.

For A-students, the page also gives a projected AP score band.

Where the points went

  1. 1. Setup. Q4, Q7. Right answer, no work shown. 5 points.
  2. 2. The “because.” Q9. Right conclusion, no reasoning written. 3 points.
  3. 3. Time. Q12–⁠13 left blank. 6 points.

Points, by cause

Setup 5
Reasoning 3
Time 6

29 points lost. 14 of them on chemistry already known.

This test could have been 85

Worked example

Q9 as written: 1 of 4. Q9 with the reasoning: 4 of 4.

Next test: Thursday, Oct 29

  • Each week until then: 2 timed sets, setup written out every time
  • Monday, Oct 26: a short mock, timed like the test
  • Every “explain” question: write the “because”
  • Leave alone: Lewis structures (already solid)

Why it's free

We won't tutor a gap we haven't measured. And you should judge us before you pay us.

It's a $497 product. Yours is free.

So what's the catch?

On the call, if you want to hear it, we'll tell you what we'd do about it and the price. That's it. You keep the page either way.

Who it's for

AP Chemistry, Biology, Physics or Calculus students in grades 10–⁠12. Especially after a test that didn't match the effort, or an A that may not hold up in May.

Questions about the Gap Map

All the questions, answered

No test at home?

That's common. Tests often stay at school. Tell us in one line what happened, and the session's timed set from that unit does the rest.

What does my kid do in the 45 minutes?

A short timed set from the unit just tested, plus the last test if it came home. Then one exam-style question, scored the way the College Board scores it, the missing step shown, and redone right.

Your kid holds the pen the whole time. It opens with what they already do right.

Do I need to be there?

No. The session is just your kid and the tutor. The call afterward is just you.

Is the session recorded?

Yes, so the tutor's findings go into the report word for word. Want the recording? Just ask.

My kid has an A. Is this still useful?

Often the most useful. An A in class doesn't always hold up in May. For A-students, the page includes a projected AP score band.

Is it really free?

Yes. No card, no enrollment. On the call, if you want to hear it, we'll tell you what we'd do and the price. You keep the page either way.

Which subjects and grades?

AP Chemistry, AP Biology, AP Physics (1, 2 and C) and AP Calculus (AB and BC), for students in grades 10–⁠12.

The next test grades the same gap as the last one.
