I'm currently a junior pursuing my BS in Mechanical Engineering. The workload is difficult but the material I'm studying is interesting, albeit some more than others. I am currently taking an introduction to materials science course and feel like I've found something I would possibly like to pursue with a masters degree. I love how applicable all of this knowledge is. What I'm asking is what can I do with just a BS in Mechanical Engineering and what could I do if I also got an MS in materials science and engineering ?
