Weekly challenge
Ten multiple-choice questions on symbols, groups, trends and electron structure. Everyone gets the same ten this week; a new set arrives every Monday. Instant marking, and a result code at the end that your teacher can check.
Ready?
Add your first name if your teacher asked for a code. It stays on this device and only feeds the code.
How it works
- The ten questions come from the same data as the bubbles and the worksheets, and change every Monday at midnight.
- You can retake it; only you and your teacher know which attempt you report.
- Teachers: collect codes with the class results page. No accounts, nothing stored online.
