It sounds like you're in a position where the JW heritage is all the cards you have to play with. Now, you can say play your opponent not your hand and bluff with JW stuff. Do you have technical / computer work experience / hobbies? Can you apply as an 'undeclared major'? If you do that, you might take intro math, intro chemistry, intro engineering (open to non-Chem Engr students) and gain some insights and leverage into your formal application to the College of Engineering / Chemical Engineering.
If that's your picture, it would appear you have a lot of years to make mistakes and prevail against them. You can parlay that youth against the red pill, Your in-JW experience will not assist you in *matriculating into* *Chemical Engineering*. I say this as someone who carefully considered every interesting degree program that the U Arizona offered, and picking that one because I heard it was the hardest and made the most money after graduation. I was a JW, I had gotten out, I was owed some kind of ordinary, if belated, "worldly" existence, I wanted to get mine, I'd show them what I was made of, etc, etc. If I could go back to the moment I started questioning my ability to get through the math, my present self would tell my past self, "You are twenty-six years old. You CAN take the time to cover all the necessary bases for success."
And go talk to an academic advisor. This is what they're paid for. Don't spill the JW beans like to a confessor. No one frankly can give a rat's ass. It's 2014. That cult should be illegal. Just get their take on how while holding only a few cards.
If you get into a science and engineering program, the good news is: Your exiting-JW experience *might be able to help you in a degree if you were doing as the Boereans did, and used the scientific method, testing out to see if this or that bullshit, this or that theory, was true. Remember that you have many years, and several months spent carefully Now, maybe a year (yes, or two) can save decades, quarters of centuries, of financial angst.
