Hello,

First of all it is not Mandatory for all the students to have laptops during their BTech. And the students with branches like CSE and IT, may need to have laptops due to their Specializations and for learning Coding Skills and All during their academic years. Other than that it is not necessary for rest of the branches. Also it may depend upon student to have a laptop for other branches  like Core, in their 3rd of 4th year of their BTech.

Hope this information will help you, Good Luck!!!
