What I should do during the winter vacation

The last class was over today. There are three finals and a project need to do. I think it is necessary to make a plan before the beginning of the vacation, which could make the plan more aggressive and ambitious. Now what is in my mind is as followed:

1. do some ACM-ICPC problems. The best way to do it may be not by “Interview street”, as Lanbo told me that the problem there is a little complicated. I think I could find some problem from those blogs. I think I could do 30 or 40 and ensure the answers are correct;
2. Get more familiar with CUDA, OpenCV, numerical calculation and matrix computation;

There may be something more, to be continued.
