Does anyone have any recommendations for studying for the BMST?

You will be fine. My gt was 111. And I did not graduate from high school. later I got it up to 136. They call me mr GED or just Chief.

PFC Freeman, there is plenty of information on here about reclassing to 12P. I know I personally have written roughly 5 comments on the requirements. The class is math intensive with a heavy concentration on electrical and mechanical engineering concepts. If you study your math/physics basics and your engineering basics you’ll be fine. The BMST is difficult but not impossible. I scored a 72 on it without any studying and I’ve been out of school for 10+ years. If you search through here and still have unanswered questions, feel free to pm me.

I have done great things in my life. I have always believed that anyone can do anything if they want to badly enough. I have a HS diploma, two Army MOS diplomas, and a bachelor's degree. I have taken many tests. I had to switch my MOS once because I could not find an available slot when I was in the reserves. If you want it, you got to work for it. It'll be worth it.
