As above. Unless you do not meet the entry requirements for a BS course. Then you would perhaps need to look at achieving another qualification first. What is your education back ground thus far?

Same thing everyone has said...but try to get into an ABET accredited program. Many universities offer engineering degrees that are not accredited and many employers ask for ABET accreditation standards. If you don't have a university that offers ABET accredited engineering courses near you, I suggest looking into ASU online engineering degree.
