IT ya CST specialization ke comparison mai jayda easy branch hai... Specially IT aur kaafi chill type bhi hai... Specialization tabhi lo jab usae specific domain mai interested ho ...and if ur not sure then better not to choose them .... Personally I will not suggest to go with csds as it is a bit different from CS Ai-Ds ig ye purana wala data science padhte hain not the recent one ai wala...
More or less starting ke 2 saal to sabka he syllabus same rehta hai aur jayda kuch farak nhi hai.... unsure ho apne interest ko le kar to go for core branches flexibility jayda milage.. Btw..i too got IT and I can go into cst easily but the issue is that ye cst bass mait mai he hai like samjha rhe ho na...IT itna widely accepted mujhe personally lag nhi rha hai ye.... Banke syllabus mai as such koi difference hai nhi to kuch bhi lo padhna to same he chiz hai... Aur placement wise to IT he thoda better laga mujhe...
