Research / Study Mode
Turn on Study Mode to run a pre-test → simulation → post-test session and
log anonymous data on this device (exported as CSV, nothing is uploaded). The pre-test and post-test use
two matched forms so students cannot simply memorise answers. Leave it off to use the plain simulation.
Privacy. No names, logins, IP addresses, or personal details are ever collected. Each response
is stored only against an anonymous session code. This anonymised data is used solely by the app
designer to improve the questions and the simulation so that better learning is achieved.
