What can I choose?

As I have mentioned in my profile, I’m a computer science student. To answer this question you might require to know some things about me,” I can do programming. I’m little hesitant to learn web development because its new to me(when I started learning HTML, it made me crazy) And well I’m learning CCNA”.

Now my college offers four value added courses which are Cloud computing, Software testing, Ruby on Rails and Android.

I don’t know which one is suitable for me. Actually I don’t have an area of interest. Let’s say that I don’t know to choose my area of interest. I don’t really know how to put these things(CCNA and Programming) together. And now, I’m confused with what I’m supposed to choose next.

Note: I’m gonna try to learn all the languages that are helpful for developing web app because I’m willing to participate in a project contest coming next year.
