I am completing diploma in computer engineering so i can get admission in bsc it direct second year

Yes, you might get admission for B.Sc in direct second year although it depends on the college and varies from one to the other.

B.Sc in Information Technology at BVU ADITM is of 3 years duration program. The eligibility criteria is 10+2 with PCM. Hence, Diploma engineering students are not eligible for this program.
