Communication Issues

Sometimes I feel we don't get as much explanation as needed in class than we actually do. For example, when making this book it wasn't until I finished building my book that I saw, at the bottom of the document made by Tom for everybody,  that he wrote that we shouldn't cut on the bleed lines because it would cut off parts of the pages we didn't want cut. Since this wasn't really ever mentioned in class, my book now has some craft issues which will overall deduct from my grade.
