Hello,

Admission process for BTech is through Jee entrance.

The one who has completed 10+2 with science stream can apply after application form releases through online mode.

The eligibility criteria for the course B.tech CSE is students have to qualify 10+2 with minimum 55% marks from a recognized institute.

Almost each and every college conducts its own entrance examination for admission to BTech Computer Science course but some offer through Jee .
