Perhaps not a short-term solution, but an egg yolk mask is also supposed to be good for the skin. It's a good source of Vitamin A, which is supposed to help promote healthy skin and decrease pimples. Other than that, there are the already-mentioned products/methods. Proactiv is supposed to be really good, but not sure you'd get your hands on it before Friday.
FYI, I've also tried out and used the toothpaste method--it works at drying out the pimples, but they don't go always away right the next day. I'd recommend putting an old pillowcase on your pillow if you plan to sleep with it on so as not to get it all over the place on a nice case.
