Amazing graphics and sounds. Everthing runs smoothly and fits the theme perfectly. Overwhelming feeling is very accurate (A+ for simulation). Only downside is the gameplay which gets repetitive very quickly. I would maybe experiment with adding minimal required amount of HW you need to finish for each subject, possibly scalling down the assignments and adding obstacles you need to avoid when dragging paper like coffee mug. This is just my stream of thought as I'm writing this, if you plan on further development (if you do keep me posted ;)). Overall, great job.
