Hello,

No, you cannot pursue B.Tech Computer Science and Engineering after pursing ITI. You need to study and pass in 10+2 with Mathematics, Physics and Chemistry or 3 year Diploma in Engineering from a recognised board to pursue B.Tech in Computer Science and Engineering. There are various entrance examinations conducted in National level, state level and University level for admission to B.Tech. You need to appear for the entrance examination on fulfilling the eligibility criteria. Few colleges give admission in basis of marks scored in the qualifying examination that is 10+2 or it's equivalent. Here is the link to the list of Entrance Examinations for Engineering
