I will attempt to clarify some of my statements. I recently returned to school enrolling at the University of Alabama in Birmingham (UAB). In this endeavor I had to obtain transcripts for high school, secondary school, and take an entrance exam.
Of my secondary school credits I was given recognition for one class, Trigonometry. I have no idea how you could recieve a Trig credit without other math credits but alas it happened.
With that said you need to obtain all previous educational transcripts then decide on a path to follow. If you have numerous years working in an engineering type position then any paper stating BS may suffice. Only you can decide if what is offered is what you really want.
If you want a "bona fide" i.e. degree that should be accepted anywhere then look into taking classes at local universities or community colleges with transferable credits.
As mentioned the requirements for most BS degrees is 128 credit hours, the first 64 are usually "core" classes that can be applied toward any degree.
What you need to do is determine what "core" classes you may need and try to take as many of those that you can online, start simple to make sure you have the time, place, etc to fulfill this classwork.
I do not remember the exact numbers but a 3-4 credit hour class may take 8-10 hours of your time. Some classes, even when they have a classroom, have most of the work or testing done online. This can be expected of many math classes now.
Psychology 101 I took as a lecture class, it was basically read the book and memorize. I thought it was easy, the hard part was it required you to participate in "studies" etc which were not part of the classroom, not sure how this works online.
Chemistry is another that may be wierd if done online. I could learn the information but they had a tendency to test in a different manner then was taught; if that makes sense. Plus this and other classes usually require lab classes which work better if done in person.
Its all in the planning, you do not have to go for an online degree in my opinion, just find classes you need to fulfill requirements then at a later time work on attending your school of choice.
I think many schools these days are a ripoff, try and stay with community colleges and universities.
FYI, ABET has a site where you can find schools in your area etc

I mentioned Indiana University and their distance learning program in a previous post, it is in the ABET list.
