Joliette,
I am doing the same thing. I am working on my bachelor degree in engineering. I can't answer the question about Bethel, but I wanted to say GOOD FOR YOU!!!
I was born in and am currently 38 years old. How much easier would it have been if we were encouraged to go to college when we were young with less responsibilities and more time to devote to our learning.
My twin brother went back as an adult and is now a practicing attorney. It's sad that so many fine young intelligent JW's willl be relegated to scrubbing toilets, cleaning carpets, or working night shift while they pioneer when they should be getting an education.
