The best part of a quiz everyday is that in addition to the testing effect, you can easily fit in the spacing effect and interleaving effect. It’s a rock solid combo, that is well studied. We have pretty strong evidence that it works for all students in all domains.

I actually like this idea - makes sense at face value - as long as they design the test in such a way that it aptly applies the knowledge instead of just learning for the sake of passing test like questions...
