Hi,
I think it would be helpful to delay displaying the possible answers or letters for typing your answers in the app for 3 seconds (maybe adjustable), so that you REALLY have to think about your answer.
Displaying the possibilities for multiple choice or letters for typing right away makes getting the answer a lot easier.
Often enough, you don’t really know the exact answer but can exclude others.
Delaying the choices would make you think more.
This refers not only to the Language Quarters but all courses.
Thanks and bye,
JN
