I also took the STEM approach and did my undergrad long before I left, having two rather liberal, slightly older JW friends that made it possible for me to go college as a JW. I earned a B.S. in Telecommunications Management at the time, (that was 25 years ago). I much more recently earned my masters of engineering in Networked Information Systems with a concentration in business practices. I am quite certain I would not have pursued a masters, had I remained a JW.
I certainly do not regret any of that, as it allowed to be become quite successful over the last 22 years or so. However, if I had not been raised a JW, I likely would have taken a more pure science route and majored in physics. I still plan to work on a doctorate in electrical engineering.
