For me, I think that a “perfect class” would be one where the material that we’re learning will actually be things that we’ll use everyday, either now or in a few years. Just knowing that the things we’re learning wouldn’t just be shoved into the depths of our mind is enough. Of course, that’s not the only thing that makes a class perfect. The teacher would need to be able to motivate us to learn and explain the material in an easy but entertaining way. Also free snacks and break time where we’ll play seven up would be a nice plus.
