IIITs are known for their tough curriculum and IIIT Allahabad is no different. The IT branch will, however be less hectic compared to CSE branch. But, they are very strict about assignments, reports and academic stuff. You would have to work hard to excel in your course. In addition to that, you will have deadlines for completing your assignments and marks will be deducted if you don't submit on time. Short attendance is also not tolerated. They are very strict about academics. However, you should focus on your goals and try to keep doing college work side by side. But, if you have cleared the cutoff, I think you're ready for working hard.

Wish you all the best.
