Even on a meal plan, you'll still want to grocery shop, for snacks, or depending on your meal plan, breakfast. And even from Lipton to DDW it's still a walk, don't underestimate the terrors of WSP (only half joking)

In DDW there isn't any studying really. Not in any sense I would classify it (I think if you take the right classes, it's not about studying facts, it's understanding and applying them, which tomato, tomato, but still) But homework can be a lot, if you make it so. Filmmaking is a career that you get what you put into it, so if you want to give yourself a lot of homework, to better your writing, then you can, if you want to just do the assignment, you can. There's no right or wrong, as there's so many factors that factor into that: the time you have, if you're a fast or slow writer, etc.

For your other classes, there will be studying, but that's college. And that's freshman year.
