I went back to school for engineering. I already had a 4 year degree that I bought and paid for and earned myself. I ahve 3/4ths of a 2 year degree in Enginnering Science (civil) and had planned to get my PE.
Then I got a better job and so I am here now and not in school.
I had a 4.0 average in Engineering school... and I worked FT and went thru a divorce and a few moves in all of that.
I am thinking of taking a different path now.. and going for more chemistry and more math. I was very good in chemistry.
Yes.. it all takes a lot of time.. but I keep chipping away at it even tho I am 51 and it is likely not going to be too useful. It is a rush to do it and find out I am good at some of this academic stuff that is considered hard to do.
