Well, when it comes to IT industry, extracurricular activities won't pay much unless they are related. For example, if you have done an exceptionally good project or if you had presented a good whitepaper or if you have won any communication (english) related compitition etc, they might count.

But at the end of the day, these extra curricular activities count only when they have to decide between two people who - according to the recruiters- are equally good. Otherwise, everyone will have to write an aptitude test, everyone needs to undergo GD and all the other rounds.

Acadamic abilities are rated far above extra-curricular activities in most of the companies.

So, give highest priority for your studies, all these extra curricular "thingy"s can be given lower priority.

If you need more specific explaination, let me know. Will post another post
