Two of ten exchanges.

How it works.

A twelve-minute spoken exam per topic. Each transcript is scored blind. Passing pays out.

Step 01

Pick a topic

Every one on the board shows what it pays before you start.

Step 02

Learn it your way

Take a day or take a month. Use any source you trust. Nobody is watching this part.

Step 03

Sit the exam

Twelve minutes, spoken, in real time. Explain it, defend it, then apply it to a case you have never seen.

Step 04

Get paid, then move on

Passing pays out and closes the topic for good. The only way to earn again is to understand something new.

What every exam measures.

Each transcript is scored blind and independently across four dimensions.

Dimension A

Accuracy

What you said is true. You catch your own slips before the examiner does.

Dimension B

Depth

The examiner asks why, twice more, on your weakest sentence. You hold the line.

Dimension C

Transfer

You apply the idea to a fresh scenario generated for your exam alone.

Dimension D

Epistemics

You name where the idea breaks down and what would change your mind.

Passing requires a score of 3 or higher across all four dimensions. Understanding is demonstrated through accuracy, reasoning, application, and judgment.

Fail and you still get the transcript.

Every transcript is scored line by line. Each dimension shows its score. The sentence where the understanding ran out is identified. The topic can be sat again after seventy-two hours.

The feedback costs nothing either way.

One short. The transcript shows the sentence where it went.

Why would anyone pay you for this?

How the payouts are funded, what happens to the recording, how topics are scored, and what the exam costs you.

Where the money comes from

The payouts come from one person’s pocket. The pilot is capped at a hundred people, and it is funded personally. A foundation funding a topic, or a company paying to verify a record, would be announced on this page before it happens.

What happens to the recording

Every exam has a recording and a transcript. Both are used only for grading and handed back to you. Delete either at any time; the pass stays on your record.

Whose idea of correct is this?

The topics have settled answers. A quarter of every mark is for naming where the idea breaks down and what would change your mind about it.

Why passing closes a topic for good

A passed topic is retired. The only way to earn again is to understand something new.

What it costs you

Nothing. No entry fee, no subscription, no card on file. Failing costs the seventy-two hours before you can sit that topic again.

Which payout methods are accepted

Right now, PayPal. Set the email on your PayPal account in your account settings and every pass pays out to it. Bank transfer and Stripe are being set up next — more methods are on the way, and they will be announced here the moment they are live.

A certificate says you attended. This says you can be questioned.

Every pass is a recorded exam you could be asked to defend again. Over time that record is worth more than the payout that prompted it.
