A fresh 10-question hardware design challenge drops every Monday. You have the week to take it, on a timer.
Auto-graded instantly. Knowledge ranks first; speed breaks ties. The board freezes and publishes when the week closes.
Every attempt earns lifetime points and feeds your streak. Everyone unlocks badges along the way — for your 1st, 5th, 10th, 25th, and 50th challenge, and for 5, 10, and 25-week streaks — plus tier upgrades from Bronze to Platinum.
Review explanations and see your weak topics linked to the right course. Once the week closes and final ranks are in, the top 3 finishers earn the Champion/Podium badge and their weekly podium count goes up.
