If so, How do you do it?  Pros and cons? 

I'm going to take one class over Winter break, It starts the 17th or 18th of December and runs through the the second week of January.  This is normally a 15 week class condensed into one month, I know it's going to be tough and I think I'm ready for the challenge.  The closest I've done to anything like this was a Summer semester where I took two classes over the course of 8 weeks, It really wasn't as bad as I thought but this one has me a little more nervous.  Any btdt, advice or tips appreciated, Thanks!
