Pick topics and how many problems, and get a link. Whoever opens it works through the problems
one at a time, checking each answer, and gets a score at the end. No accounts — the whole set is in the link.
At the end, each student gets a line to send you. Paste them all into
Class results to see who missed which problems — this set is remembered on this device, so its problems show there too.
The problems
Check a result line someone handed in
Paste the line from the end of a practice set. It says whether the score was changed after it was copied.
