Last 20 days in MIT

Today is the first day of IAP, in which MIT students have a one month break just to do whatever they want before the Spring semester starts. Some people would do a MISTI to travel around the world (for free), get some credits, do some fun classes, pickup skiing/snowboarding etc.

I am officially leaving on Jan 20. So unfortunately I couldn't take any of the serious classes. Ref:

There are 2 online/offline classes I am most interested in:

And also I would want to do a ski trip, work on the researches projects and catchup with all the amazing people I have met here!
