<p>There is so much overlap between math and physics and most kinds of engineering. You don’t have to make this decision right away because the first year will be very much the same no matter what you ultimately choose–freshman English, calculus, other stuff–it’s only until at least year two that the majors (math, physics, engineering) start differentiating themselves. Even then there’s a lot of overlap. I’m an engineering physics major, I take a lot of math. Sit tight, make up your mind later. I changed my mind about my own major after starting, originally I was going to be Comp.Eng.</p>
