Hello,

hope you are doing well,  There is not much difference between IT and CS. It depends on your interest. If you are interested in only coding then you should opt. IT and if you are interested in Coding and the Hardware part too then you should go for CS. If you are going for IT then there is no such need to study physics and maths but in CS branch you will be taught maths and physics so at the end it's about your interest.

I hope you find this information helpful. I wish you all the best for your future.

Good Luck.
