B.E. CSE is a 4-year undergraduate program in the study of the application of engineering tools in computer science. The eligibility for the program is qualifying 10+2 in Science stream with an aggregate of 50% or equivalent GPA. The average course fee ranges between INR 63,000 to 7.43 Lacs, which is subject to vary for different institutions and colleges.
