As a student, it is important to understand things and learn how to do stuff. It is not a bad thing to amass a broad knowledge, if you feel comfortable with that. I did the very thing while I was a Bachelor student and it still helps me a lot. People from all over the BU come over to me and ask for help automating different things in different languages. Just last week, I had to add Perl to my repertoire, which was very easy because I already know logic and many similar languages ;)
While you might think that you are on the best way to becoming a jack of many trades, master of none, the time as a student is actually the best time to build such a broad base. Later on, when you work for a company, they will most likely want you to become an expert for a single technology. However, at this point in time, you don't know what that might be, so you can just do what you want and then leave the decision to the job description you get later on.
