Summatives

How can one project summarize all the knowledge you have been privileged to receive in a semester? Over the course of a semester we just learn so much and there is such a significant amount of material covered. To fit such an impressive amount of work into one summarizing assignment cannot be done as the amount of material covered cannot be justified in merely one project. I am not saying there should be more summatives, but I feel they should not be as heavily weighted as they are, because they do not get the results they are aiming for. Just a thought.
