Thank you for the detailed response.
So if I don't plan to get into phD + want easier admission, Nuclear.Eng (Engineer's degree for NE) is the way to go I guess. However, I've noticed that for Berkeley or MIT, the N.Eng course requirements are more intensive than M.S.
N.Eng: 162 credits + thesis (2 years)
M.S: 66 units + thesis
"The program for an engineer's degree requires more advanced and broader competence in engineering and science subjects than for the master's degree, but with less emphasis on original research than a doctoral program."
I guess M.S. requires more research while N.Eng focuses on courses. I'm still slightly unconvinced that the Engineer's degree program is easier to get in than the M.S. program.
Thanks again~
