I hope I don't have to spell out the crazy power the cushion gives you, but just in case, you can visualize your entire semester and see if there are any big roadblocks to getting good grades. The golden rule is: not enough time, not enough straight A's. The moment you feed Shovel information, it turns into a crystal ball. It can see if you're starting too late or if you're trying to do too much. It gives you all of the information you need to make the right decisions about your time.
