<p>Stonebridge, I think I’m friends with your son, unless there’s another physics/math/econ major in the same grade.</p>

<li><p>Most classes are taught by profs, but you will have occasional post-grad or grad student classes. I’ve found that my best teachers are usually post-grads, it’s not always a good thing being taught by an out of touch academic.</p></li>
<li><p>It varies greatly by teacher and class, there’s no uniform answer to say.</p></li>
<li><p>Majoring in more than one thing is very easy at Tulane because that’s how the academic programs are designed. The core reqs and major reqs are low compared to most schools, so you have more freedom to pursue other things (or take more classes in your major).</p></li>
<li><p>I’m majoring in physics and math, with a minor in studio art, and out of those three departments I’ve found that the math department is the strongest, in my opinion. There’s always a healthy selection of course offerings, many of them quite good. For example, some of the courses being offered next semester: number theory, topology, abstract algebra, real analysis, linear algebra, ODE, PDE and plenty more. </p></li>

<p>Oh, and computer science is being brought back to tulane, starting next year.</p>
