How long does it take finish B.Sc honors in CSE from Dhaka City College?Is it's degree more good and prestigious than a private university?

One more question,if a student gets 2.8 in HSC and 4.63 in SSC without optional subjects and starts reading in a private university here.can he later transfer the credits to a university in USA?Will they look at the HSC,SSC gpa with much importance?
