The weekly challenge
One circuit a week, the same one for everybody, a new one every Monday at 00:00 UTC. It is on your Home, on /learn and on Your progress, with the dates it runs (for example "Nov 9 to Nov 15"), a short brief and a What you'll learn line. Every week teaches something you may not know yet: a new part, a library or a technique, such as PWM, millis() timing, an ultrasonic sensor, a shift register or I2C.
Start opens a built-in close to what you need, in the editor. Build it, save it, then press Check my build: your newest saved project is run on the real simulator and checked against the week's checks, the same way a class assignment is graded. Not now puts the card away until next week.
Signed in, if you already did this week's challenge (in practice, say), you are given the next one you have not done, so a week never hands you a repeat.
Stuck? Need a hint? shows the first of three hints, and each press after that the next one, each giving away a little more. Hints cost nothing.
Passing it is worth 150 XP, once a week, and it counts toward your streak. The daily challenge it replaced paid 50 XP a day; the XP you earned from dailies stays yours.
Practice
Under this week's challenge, Practice past challenges lists the challenges of the weeks before, newest first. Start any of them again and, signed in, check your build. Practice pays no XP; it is there for the skill.
The weekly leaderboard
Also on /learn: experience earned since Monday.
Everyone with an account is on it unless they untick Show me on the public leaderboard, which is why the box is the first thing on the card rather than a setting somewhere else. Untick it and you are off at once, and you stay off until you tick it again. It shows a first name or a username and nothing else.
Signed out there is nothing to draw at all, because a board of one browser is not a board. The card says so in one line and offers an account.
The friends board
The same week, fed by the invite link: people who came in through your link, and whoever's link you came in through. If invites are not set up, the card simply does not draw it. See invites.
The leaderboards page
/leaderboard has three boards, a tab each, and a link can open any of them:
- Longest streaks (/leaderboard#streaks): the longest streaks still running. A streak that has ended drops off, however long it was.
- Top XP (/leaderboard#xp): the highest levels, all time.
- This week (/leaderboard#week): the weekly board above.
The same box puts you on all three, and unticking it takes you off all three. Beside the list is your own card: your streak's six days on the streaks tab, your level and place on the others. Students in a class, children under 13, suspended accounts and Mokxi staff are never listed, whatever the box says. The boards show a name or username, level, XP and streak, never an email.
Not in the classroom
None of this is on the class pages. A class dashboard is a roster and a set of submissions, and a league table of XP is not what a teacher asked for.
The weekly goal
Separate from the leaderboard and not competitive: five lesson steps a week, out of the box, drawn as a ring. Reaching it the first time in a week is worth 60 XP. See XP and levels.
