Bro you can definitely complete DAE & then go for engineering but your world would be very limited. I money is not an issue, then you can think of changing, it is never too late esp you are in first year only. BUTTTT... continueing DAE isn't that bad, you can always go for B.Tech & also, BS(Engineering) which is not accredited by PEC.. Remember no one actually cares about PEC accredation in real world. I own a PEC accredited engineering degree but I never got registered with PEC but it's been 4years that I am in job & no one ever bothered about my degree. Moreover, if I go for masters from abroad, then every Pakistani degree is useless.
