How coins, chapter tests and badges work on beMahan

Children love collecting things. We use that, gently, to celebrate the two habits that matter most: watching lessons properly and testing yourself honestly.

Silver coins: for lessons really watched

Each lesson pays 10 silver coins, once, when your child has watched about 80% of it.

While the video plays, the page sends a small “still watching” signal every few seconds. Our server checks that the video really moved forward at a believable speed. That means:

• Watching at normal speed, or up to 2× speed, counts.
• Jumping to the end, replaying the same minute ten times, or leaving a paused video in a hidden tab does not count.

Nothing is decided in the browser, so there is no button to press and no trick to find.

Gold coins: for the first try of a chapter test

At the end of each chapter there is a short question paper, usually 10 questions. It looks like a real school paper, with no timer, so read calmly.

Score on the first try	Gold coins
Full marks	50
80% or more	40
60% or more	25
40% or more	10

Only the first try earns gold. After handing in, your child sees every question, their answer, the right answer and a one-line explanation. Retakes are welcome and their scores are saved, but they are practice and pay no gold. That keeps the gold honest: it shows what was learnt, not what was remembered from the answer sheet.

A few fair-play rules work quietly in the background:

• The answers are never sent to the browser before the paper is handed in.
• Questions and options come in a fresh random order every time.
• A paper finished impossibly fast is not marked; your child is asked to take their time.

Streaks and badges

A day streak counts the days in a row on which your child finished a lesson or a test. There are also badges to collect, such as the first chapter test, full marks, 5 and 25 chapters done, 10 and 50 lessons watched, and streaks of 3, 7 and 30 days.

Everything is shown in your child’s wallet: the coin jars, the badge sheet, a report card of every chapter test, and a coin diary of what was earned and when.

What coins are not

• They cannot be bought. beMahan has no payments and no ads.
• They are not a ranking of children. There is no public leaderboard.
• They are not the goal. They are a pat on the back for showing up.

If your child is chasing coins by rushing, sit with them for one lesson and one test. The rules are designed so that the fastest way to earn is simply to learn.
