HeyPooja, there are very few colleges in Delhi University which offer a technical course and the number of colleges which offer b.tech in CSE is only one what we have found and the college is
Shaheed Sukhdev College of Business Studies

its a top college to pursue your U.G course yet there are few excellent colleges out there which offer B.Sc(hons.) in computer science

namely:-

Miranda House College.

St. Stephen's college

Hansraj college

These are some top colleges to choose from.

All the best for future.
