How do i get over a bad cold?

I woke up this morning feeling like I got hit by a bus. I'm extremely congested and stuffed up, and my chest is tight and Im coughing a lot of mucus up. Also, my body aches and I have the chills. Because I've been coughing so much, my throat is starting to hurt. How do I get over all of this? It's midterms week and I can't be sick right now!
