What is the best way to fight off a cold?

So I developed a cold yesterday and has caused me to miss work and cles. I have a runny, stuffy nose, a bad headache (more on the right side) sore throat, and a bit of fatigue, no fever yet. my question is, what is the best way to fight off a cold? I have midterms next week and need to get prepared and be mentally focused on that. Any remedies on the best way to fight off a moderate cold? or possible minor sinus infection?
