Hi

hope you doing well

Getting admission to the B.Tech CSE program at Swami Vivekanand College with 70% in your 12th boards and 70 percentile in JEE Mains  might be challenging if it's a highly competitive institution. Admission to private colleges like Swami Vivekanand College typically depends on their specific cutoffs, which vary based on the number of applicants and seat availability.

However, many private engineering colleges also consider management quota or offer seats through counseling processes that may be flexible regarding entrance exam scores. You can check the specific cutoff of the college for CSE and inquire about alternative admission pathways.

Best wishes.
