rikesh,
I doubt anyone in the airline industry will look into your non flying qualifications in such detail as to say that you're too one sided. You've found something that you're good at and you're making the most of it by getting the highest possible qualification with that strength. No one can fault you for that.
With regards to XL319's comment's, what he's saying is that having a degree won't help to get a flying job. There are much more important things to airlines than your education. Having exemplary results throughout your education doesn't mean you'll be a suitable pilot for example. What a degree will help you with however is giving you a decent fall back should you lose your medical (it happens), or lose your job when the industry goes through a downturn (aviation suffers very badly in economic downturns). It may also give you valubale life experience, though it is argued that the same life experience could be found through working for 3 or 4 years full-time.
If you did a good degree (like maths) and then got a job with that degree, you could fund your training with your spare earnings. Having done all that no airline could fault your motivation or dismiss you as not yet mature enough.
Another thing to consider is, if you are an academic, you should capitalise on that and get as high a qualification as you can. Not everyone is gifted with academic ability, so if you are I reckon you should embrace it; it can do no harm.
