I was CS/CE
Make 70s out of college or an extra 2 years of school to make 5% more (at least at my company?)
Also the 2 years you're working your salary is ~150k + benefits, vs -50k depending on what type of school you go to (I went to private)
I think its better to wait because (a) they pay for [some of] it and (b) I can go back in a few years to engineering management then move up into a lead position [maybe quicker than getting one right after grad?]
I think the 2 best options are to plan ahead and either do a 5 year masters, or wait until you are working at a company (like I am thinking about/plan on doing)
