I am Elecetronics and Communication Engineer of 2013 passout. I am placed in TCS in Campus placement. My tentive joinning is in Feb or March 2014. And Now I have 6 months free time. I know little bit of C. and little of c++. Whatched few videos of java by bucky( newboston channel of youtube). But I am little bored of watching this video. What actually you think I should do in this 6 months which actually help me in TCS?

Please give me some advice. I know you all are expert . I should follow your advice very sincerely.

Thanks in advance
