Spock and other guppies who’re in the field would be able to advise you better on this but in response to your request for*** “a neutral reply irrespective of my aptitude n interest”***, I’d just like to say that this may not be the right approach to determining what is going to be a major life decision for you. I’ve met quite a few people who chose a career path based on others’ recommendations but had regrets later about not going with their own preferences. For some, they sought to further advance their qualifications to suite their interests while others couldn’t do so.
My point here is that with a field like engineering, and selecting a discipline upfront, you’re already sort of bound into a specialization and although it may be possible to switch disciplines in your second year, there would be some penalties in terms of course credits that won’t be transferred etc. – so in a case like this, it helps to do your due diligence… ask around for others’ opinions by all means but don’t let it override your own preferences and gut feel.
