@USNA1985. I read what you said about being difficult to double major when engineering is one of your majors. Does this hold even if your other major was math? My DD is interested in doing math and engineering. She would like to validate AP-statistics, calculus, multivariable calculus, differential equations, and number theory (taken at state university). She was hoping that if she were to validate these core math classes, there would be enough overlap between engineering and math that she would be able to double major. What do you think, is it even possible?
