Hi! I was wondering what education is needed for being a System Engineer.

There are a number of different degrees that pertain to being a systems engineer. What is good to think about is the type of systems you'd be interested in working on. My undergraduate degree was in Electrical Engineering which is necessary for building electronic systems. Since there are electronic systems in just about everything nowadays, this degree is particularly helpful. However, having if you were interested in building biology based systems or combustion based systems (engines), etc. it might be more relevant to earn a degree in biology or mechanical engineering!
