Any engineers?

Hello! I've been in college studying criminal justice. I have my AS and was working towards my BS. Anyways, life happened and I went from being an A student to failing 5 classes and getting academically disqualified. I was thinking about going back to community college and looking for a different path. I was interested in engineering but I know there are many types so I would love to hear about what you studied in school, how long it took, what you do and what you make? I need a fresh start.

Thank you!
