Hello Sanjay.

This is a very tricky question to be very fair.

Let me tell you that we can say either none I'd hard or all are hard. It totally depends on our interest if you are having interest in any it will be very easy for you .

But still IT is a little bit hard due to its course content as it covers cs and ece subject also.

Hope it will help you.

Feel free to ask further queries if any.
