Test site. This is a staging deployment for trying out new features, not the live site your real students use. Adds a class of 24 made-up students (nicknames start Syn_) and practice history, so you can see the dashboard filled in. Test site only.
Only signed-in students are recorded, and only which questions they answered and whether they were right, never what they typed. Small samples are not turned into a verdict: a figure needs at least 5 answers.
