Hi Anjali,
Actually, I was also considering HR + IT, but I just opted out of it. Now, I'm focusing on core HR. When I spoke to my faculty, they mentioned that it is, without a doubt, a nice combination, thanks to the growing IT sector. One drawback is that, as mentioned in earlier posts, for a fresher, IT companies don't provide much scope; mostly limited to recruitments. Anyway, you can pursue your degree. After working for 2-3 years in the manufacturing sector, you can always shift to IT. Let me tell you, a combination of IT will get you high salaries from the beginning, but through manufacturing industries, you'll start with comparatively lower salaries.
Finally, pursue whatever you want because the scope is always there if your heart is in it.
Cheers,
Amrita
