I love Amazon, but after a high CC bill last year, I must be careful! I had a constant stream of packages form Amazon last year, just like a recent South Park episode.
I am not a CE but here are my thoughts.
You should brush up on your English and grammar skills prior to applying to any university. Engineering involves math and physics. They are considered difficult by many. I found that there were only a few difficult classes. I studied electrical...
My dad started as a draftsman and went to night school 2hrs away and got his engineering degrees. That took 17 years to graduate!!!!!! Then he got his P.E. License! He stayed at the same company the entire time and retired from there at 55yrs old.
FYI - we hire designers and they "engineer". Since most of the stuff we design is also manufactured by us, we are usually exempt from the PE requirement.
If you were calculating and figuring then you were engineering and not just CAD. It counts for experience. Some states allow math and science degrees so long as there was enough math involved for PE. Contact your state and go get your PE!
